WHAT IS READY-MIXED CONCRETE?<br />

Concrete is an important building material which is formed by mixing the<br />

aggregate (fine and coarse aggregate), cement and water with or without the<br />

addition of chemical and mineral additives, homogeneously in accordance with<br />

the production technology, with plastic consistency at the beginning and<br />

solidifying and strengthening with time.<br />

Ready-mixed concrete is prepared by a non-user person or organization and<br />

delivered in fresh condition. The concrete prepared by the user outside the<br />

construction site and the concrete prepared by the persons or organizations<br />

other than the user in the construction site are included in the definition of<br />

“ready-mixed concrete”. The concrete produced by the user only within the<br />

construction site for its own use falls within the definition of “concrete<br />

manufactured at the construction site”.<br />

Ready-mixed concrete designed with scientific methods should be produced<br />

and controlled according to the standards in modern facilities which make the<br />

component weighing automatically by weight method. There are 5 fundamental<br />

steps which determine the quality of ready-mixed concrete: • Design •<br />

Production • Transportation • Placement • Maintenance and Cure<br />

The first three steps are carried out by the ready-mixed concrete producer, and<br />

the last two steps are carried out by the consumer. Today, there is no other<br />

construction material taht is used as frequaently as ready-mixed concrete.<br />

Benefits and Advantages of Ready-mixed Concrete • Fast • Continuous<br />

availability • Possibility of control at every stage • Optimum material usage •<br />

Time and cost saving • Environmentally friendly<br />

What are the Components of Ready-mixed Concrete? The raw materials that<br />

make concrete are aggregate, cement, water, chemical and mineral additives.<br />

Cement : 13 % Water: % 7 Aggregate: % 80 According to TS EN 206-1 readymix<br />

concrete standard the conformity to own standards of all component<br />

materials must be shown.


AGGREGATE Aggregates, which are the<br />

most used component of concrete in<br />

volume, must be stored as produced<br />

according to related product standard<br />

at ready-mix concrete facilities<br />

properly. Aggregatesö which have the<br />

lowest water absorption value, and do<br />

not produce enlarging materials in<br />

concrete with cement in time, have<br />

relatively cubic particleshape are<br />

quality aggregates. Particle size can be<br />

adjusted at aggregate production<br />

facilities as needed.<br />

CEMENT They are inorganic and finely<br />

ground hydraulic binders that form a<br />

hardening paste when mixed with<br />

water and maintain its strength and<br />

stability even under water after<br />

hardening. The most suitable cement<br />

type for ready-mixed concrete<br />

producers is cement which is the most<br />

compatible with aggregate and<br />

chemical additives and provides the<br />

best response to customer<br />

expectations, providing the lowest<br />

cement usage provided that it is based<br />

on concrete classifications.<br />

MIXING WATER In addition to the<br />

mixing water added during the<br />

concrete production phase, addition of<br />

more water should be prevented at the<br />

place of use.


CONCRETE ADDITIVE MATERIALS Today, besides the additives that decrease the<br />

concrete water requirement and therefore provide more strength and<br />

economy, chemicals that affect many properties of concrete such as resistance<br />

speed, air content, impermeability, shrinkage etc. are used. Thanks to the<br />

chemical additives, it is possible to produce concretes that do not shrink<br />

anymore, are self-locating, are not affected by aggregate reactivity, are<br />

prevented from reinforcement corrosion and have superior strength.<br />

READY-MIXED CONCRETE CLASSES Classification in TS EN 206-1 ready mixed<br />

concrete standard is, the environmental impact classes according to the<br />

exposed area, consistency classes, aggregate largest grain classes, compressive<br />

strength classes and classification dependent on density. The compressive<br />

strength classes that are the most known and used ones among these classes<br />

are given below.<br />

READY-MIXED CONCRETE PRODUCTION STATIONS Concrete Plant is a facility<br />

where ready-mixed concrete components are stored, mixed under control,<br />

concrete is produced and filled into transmixers. Concrete plants are divided<br />

into two as wet and dry mixes according to mix form and bunk and star type<br />

according to storage form.<br />

WET SYSTEM READY-MIXED CONCRETE PRODUCTION The wet system readymixed<br />

concrete production is done by the mixing method in the central mixer in<br />

the concrete plant. The fresh concrete, which is prepared as all components in<br />

the concrete design recipies in accordance with the standards are mixed in<br />

concrete plants that have automation system, is transported by means of<br />

transmixers to the delivery site that is determined by the customer. Initiation<br />

and completion of the mixing process of the concrete materials are done in the<br />

central mixer in the concrete plant. The mixers used for this purpose are<br />

generally forced palet mixers.<br />

least 5 minutes at the mixing cycle of the transmixer (at least 10 rpm).


LABORATORY STUDIES<br />

As Iberia ready-mix concrete, we have adapted production with globally<br />

accepted quality and satandards, and doing research and development studies<br />

in this direction as our principle to improve the ready-mix concrete sector<br />

which has an important potential in the field of construction in Northern Iraq<br />

and Baghdad region.<br />

In our company we value laboratory and team work in high quality concrete<br />

production. Before procurement of the materials, the raw materials that are<br />

required to be delivered to the fieldare tested onsite and previous test results<br />

are checked. The physical and chemical tests of aggregates, cement and<br />

chemical additives that are delivered to the concrete field are done as daily,<br />

weekly and monthly periods. Compliance reports and mixture formulations are<br />

prepared. During concrete production phase, the factors that may affect the<br />

continuity of production in desired consistency and quality in the concrete plant<br />

are detected and corrected by the labaratory team.<br />

Another important point for concrete is the usage of chemical additives that<br />

remove the seasonal effects affecting quality and strength. The specifications,<br />

effects, and usage rates are determined appropriately to the standards by the<br />

laboratory team and usage reports are prepared. It comprises technical staff<br />

and equipment to detect harmful effects after concrete production while<br />

transporting and to instantly deal with possible negative situations. It is our<br />

duty to make fresh concrete tests during concrete pouring and collecting<br />

suitable samples from field, keeping these samples in water pools, applying 7<br />

and 28-day pressure tests on samples at appropriate dates and reporting these<br />

to our valuable customers. Besides the concrete, which is the product of our<br />

R&D and quality studies, that has high strength and conforms global standards,<br />

lightweight concrete that has low unit weights (400 -1750 kg/m³ ) and foam<br />

concrete are at your service for your special and sensitive constructions. It is<br />

necessary to take into consideration the environment, and diversity of<br />

constructions during concrete production. After determining these conditions<br />

and project details, various concrete classes in different standards are included<br />

in the production plans subsequently intense R&D and quality controls.

PILES<br />

Precast Reinforced Concrete Piles:<br />

Precast Concrete Piles may be defined as a reinforced concrete pile, which is<br />

moulded in circular, square, rectangular or octagonal form. The precast concrete<br />

piles are cast and cured in a casting yard and then transported to the site for<br />

driving. Piles can be cast and cured near the work-site if there is a long distance.In<br />

case space is available, pile can also be cast and cured near the site of works. They<br />

are driven in a similar manner as timber piles with the help of pile drivers. Iberia<br />

Company provides a big range of precast concrete piles<br />

Driven or displacement piles They are usually pre-formed before being driven,<br />

jacked, screwed or hammered into the ground. This category consists of driven<br />

piles of steel or precast concrete and piles formed by driving tubes or shells<br />

which are fitted with a driving shoe. The tubes or shells are filled with concrete<br />

after driving.The tubes or shells which are filled with concrete after driving. Also<br />

included in this category are piles formed by placing concrete as the driven piles<br />

are withdrawn.<br />

Bored or Replacement piles They require a hole to be first bored into which the<br />

pile is then formed usually of reinforced concrete. The shaft (bore) may be eased<br />

or uncased depending upon type of soil.<br />

• Concrete piles may be precast, prestressed, cast in place, or of composite construction.<br />

• Precast concrete piles may be made using ordinary reinforcement or they may be<br />

prestressed.<br />

• Precast piles using ordinary reinforcement are designed to resist bending stresses during<br />

picking up & transporting to the site & bending moments from lateral loads and to provide<br />

sufficient resistance to vertical loads and any tension forces developed during driving.<br />

• Prestressed piles are formed by tensioning high strength steel prestress cables, and<br />

casting the concrete about the cable. When the concrete hardens, the prestress cables are<br />

cut, with the tension force in the cables now producing compressive stress in the concrete<br />

pile. It is common to higher-strength concrete (35 to 55 MPa) in prestressed piles because<br />

of the large initial compressive stresses from prestressing. Prestressing the piles, tend to<br />

counteract any tension stresses during either handling or driving.<br />

• Max length: 10 - 15 m for precast, 20 - 30 m for prestressed.<br />

• Optimum length 10 - 12 m for precast. 18 - 25m prestressed.<br />

• Loads for usual conditions 900 for precast. 8500 kN for prestressed Optimum load range:<br />

350 - 3500 kN.


BRİDGE BEAM<br />

Bridge beam is an element that can easily pass through large openings<br />

using high strength (C 40 and higher) concrete and prestressing<br />

technology, which is generally used in highway projects. Prestressed<br />

bridge beams are manufactured in different dimensions and cross<br />

according to the technical specifications of the bridge to be crossed. One<br />

of the advantages of the Prefabricated Bridge Beam is that it can save<br />

time with the passage of wide openings and the short construction<br />

period. Prefabricated reinforced concrete “I” cross section bridge beams<br />

are the indispensable prefabricated elements of bridge/viaduct<br />

construction due to their speed, quality and low cost features.


WATERPROOF CONCRETE<br />

Design and construction of a watertight concrete<br />

structure is a system approach. The water<br />

impermeability of a construction is determined by<br />

fulfilment of the decisive requirements regarding<br />

limitation of water permeability through the<br />

concrete, the joints, installation parts as well as<br />

cracks.<br />

Long lasting, durable watertight constructions are<br />

achieved by application of a well defined,<br />

engineered system. All involved parties have to<br />

closely interact in order to minimize the<br />

probability of mistakes.<br />

Waterproof concrete is normally an impermeable<br />

concrete. To obtain an impermeable concrete, a<br />

suitable particle-size distribution curve must be<br />

generated and the capillary porosity has to be<br />

reduced.<br />

Water absorption of concrete under pressure<br />

measures the maximum water penetration in mm<br />

after a defined time with a<br />

specified pressure.<br />

(72 hours with 5 bar according EN12390-8)


MEASURES TO REDUCE THE CAPILLARY POROSITY ARE<br />

AS FOLLOWS<br />

Reduction of w/b-ratio<br />

Pore blocker to further reduce the water transport<br />

Shrinkage reduction (dry and plastic) to minimize crack formation<br />

Additional sealing of the voids with pozzolanic reactive material<br />

The concrete curing process is the final parameter affecting the<br />

water resistance<br />

Concrete Composition<br />

AGGREGATE<br />

Well graded particle-size distribution curve<br />

Fines content of the aggregate kept low<br />

Adjustment to the binder content is usually necessary to<br />

obtain a satisfactory fines content.<br />

CEMENT<br />

EN 206 Minimize paste volume as for the recommended<br />

application<br />

ADDITIONS<br />

Use of pozzolanic or latent hydraulic additions<br />

WATER CONTENT (W/B- RATIO)<br />

Low w/b-ratio to reduce the capillary porosity<br />

PLACING<br />

A plastic to soft concrete is recommended to produce<br />

waterproof concrete,<br />

Careful and correct compaction of the concrete is important.


CURING<br />

Immediate and thorough curing is essential<br />

Impermeability of concrete against water is determined by the impermeability of<br />

the binder matrix, i.e. capillary porosity. Decisive factors for the capillary<br />

porosity are the w/b-ratio as well as the content and type of pozzolanic or latent<br />

hydraulic materials. A powerful superplasticizer is used to lower the w/b-ratio.<br />

This in turn decreases the volume of capillary pores within the concrete matrix,<br />

while lending the concrete high workability. These pores are the potential<br />

migratory paths for water through the concrete. With application of water<br />

resisting admixture the calcium in the cement paste produce a hydrophobic layer<br />

within the capillary pores. This consequently blocks the pores and provides<br />

effective protection even at 10 bar (100 meters head of water). The concrete<br />

should be placed, compacted and cured in accordance with good concrete<br />

practice. The correct system for jointing (movement joints, construction joints) is<br />

the key to achieving a watertight structure. Concrete pour sequences and bay<br />

sizes need to be considered in order to reduce the risk of plastic shrinkage<br />

cracking. As a guide, an aspect ratio not exceeding 3:1 is suggested for wall pours<br />

in particular.<br />

Iberia waterbars are flexible preformed PVC waterstops for the waterproofing of<br />

both movement and construction joints which can be subjected to low and high<br />

water pressure.<br />

Correct design of any joints is essential on the one hand. On the other hand proper and<br />

careful installation of the jointing system is decisive for achieving watertightness of<br />

constructions. If watertight concrete leaks, then most often this is due to poor joint<br />

construction. In addition other details such as tie bar holes and service entries need to be<br />

considered. Depending on the level of protection against water, i.e. outside water pressure<br />

as well as intended utilization of the construction, different joint systems are available.<br />

Non-movement joints are usually sealed using hydrophilic strips which come in various<br />

shapes and sizes and swell on contact with water. Where a structure requires a higher<br />

level of protection, more advanced joint systems are available which may offer a<br />

combination of hydrophilic elements built into a resin injected hose. This provides an<br />

excellent secondary line of defense. Where movement joints are necessary, these can be<br />

sealed using hypalon strips secured internally or externally using special epoxy adhesives,<br />

or traditional PVC water bars. Immersion and permanent water contact. The water<br />

permeability limit for watertightness is defined as 10 g/(m2 x hours) (according to SIA<br />

262/1), where water permeability is smaller than vaporizable volume of water without<br />

pressure over a defined period.

23 TYPES of CONCRETE and THEIR APPLICATION<br />

Different types of concrete are produced based on the<br />

constituent material, mix design, the method of<br />

construction, area of application, form of hydration<br />

reaction. Details of these various types of concrete, their<br />

1. Normal Strength Concrete<br />

The concrete that is obtained by mixing<br />

the basic ingredients cement, water and<br />

aggregate will give us normal strength<br />

concrete. The strength of these type of<br />

concrete will vary from 10 MPa to<br />

40MPa. The normal strength concrete<br />

has an initial setting time of 30 to 90<br />

minutes that is dependent on the cement<br />

properties and the weather conditions of<br />

the construction site.<br />

2. Plain Concrete<br />

The plain concrete will have no<br />

reinforcement in it. The main<br />

constituents are the cement, aggregates,<br />

and water. Most commonly used mix<br />

design is 1:2:4 which is the normal mix<br />

design.<br />

The density of the plain concrete will<br />

vary between 2200 and 2500 Kg/meter<br />

cube. The compressive strength is 200<br />

to 500 kg/cm 2 .<br />

These types of concrete are mainly used<br />

in the construction of the pavements and<br />

the buildings, especially in areas where<br />

there is less demand of high tensile<br />

strength. The durability given by these type of concrete is satisfactory to high<br />

extent.


3. Reinforced Concrete<br />

The reinforced cement concrete is defined as the concrete to<br />

which reinforcement is introduced to bear the tensile strength.<br />

Plain concrete is weak in tension and good in compression.<br />

Hence the placement of reinforcement will take up the<br />

responsibility of bearing the tensile stresses. R.C.C works with<br />

the combined action of the plain concrete and the<br />

reinforcement.<br />

The steel reinforcement used in the concrete can be in the form<br />

of rods, bars or in the form of meshes. Now fibers are also<br />

developed as reinforcement.<br />

Fiber reinforced concrete are concrete that use fibers (steel<br />

fibers) as reinforcement for the concrete. Use of meshes in<br />

concrete will give ferrocement.<br />

Whatever be the type of reinforcement used in concrete, it is<br />

very necessary to ensure proper bond between the concrete<br />

and the reinforcement. This bond will control the strength and<br />

the durability factors of the concrete.


4. Prestressed Concrete<br />

Most of the mega concrete projects are carried out through<br />

prestressed concrete units. This is a special technique in which<br />

the bars or the tendons used in the concrete is stressed before<br />

the actual service load application.<br />

During the mixing and the placing of the concrete, these<br />

tensioned bars placed firmly and held from each end of the<br />

structural unit. Once the concrete sets and harden, the<br />

structural unit will be put in compression.<br />

This phenomenon of prestressing will make the lower section of<br />

the concrete member to be stronger against the tension.<br />

The process of prestressing will require heavy equipment and<br />

labor skill (jacks and equipment for tensioning). Hence the<br />

prestressing units are made at site and assembled at site.<br />

These are used in the application of bridges, heavy loaded<br />

structures, and roof with longer spans.<br />

5. Precast Concrete<br />

Various structural elements can be made and cast in the factory<br />

as per the specifications and bought to the site at the time of<br />

assembly. Such concrete units are called as the precast<br />

concrete.The examples of precast concrete units are concrete<br />

blocks, the staircase units, precast walls and poles, concrete<br />

lintels and many other elements.<br />

These units have the advantage of acquiring speedy<br />

construction as only assemblage is necessary. As the<br />

manufacturing is done at site, quality is assured. The only<br />

precaution taken is for their transportation.


6. Lightweight Concrete<br />

Concrete that have a density lesser than 1920kg/m 3 will be<br />

categorized as lightweight concrete. The use of lightweight<br />

aggregates in concrete design will give us lightweight<br />

aggregates.<br />

Aggregates are the important element that contributes to the<br />

density of the concrete. The examples of light weight<br />

aggregates are the pumice, perlites, and scoria.The light weight<br />

concrete is applied for the protection of the steel structures and<br />

are also used for the construction of the long span bridge<br />

decks. These are also used for the construction of the building<br />

blocks.<br />

7. High-Density Concrete<br />

The concretes that have densities ranging between 3000 to<br />

4000 kg/m 3 can be called as the heavyweight concrete. Here<br />

heavy weight aggregates are used.<br />

The crushed rocks are used as the coarse aggregates. The<br />

most commonly used heavy weight aggregates is Barytes.<br />

These types of aggregates are most commonly used in the<br />

construction of atomic power plants and for similar projects. The<br />

heavy weight aggregate will help the structure to resist all<br />

possible type of radiations.<br />

8. Air Entrained Concrete<br />

These are concrete types into which air is intentionally<br />

entrained for an amount of 3 to 6% of the concrete. The air<br />

entrainment in the concrete is achieved by the addition of foams<br />

or gas – foaming agents. Some examples of air entraining<br />

agents are resins, alcohols, and fatty acids.


9. Ready Mix Concrete<br />

The concrete that mix and bathed in a central mixing plant is<br />

called as ready-mix concrete. The mixed concrete is brought to<br />

the site with the help of a truck-mounted transit mixer. This once<br />

reached in the site can be used directly without any further<br />

treatment.<br />

The ready-mix concrete is very precise and specialty concrete<br />

can be developed based on the specification with utmost<br />

quality.<br />

The manufacture of these concrete will require a centralized<br />

mixing plant. These plants will be located at an adjustable<br />

distance from the construction site. If the transportation is too<br />

long then it will result in setting of concrete. Such issues of time<br />

delay are cope up with the use retarding agents that delays the<br />

setting.<br />

10. Polymer Concrete<br />

When compared with the conventional concrete, in polymer<br />

concrete the aggregates will be bound with the polymer instead<br />

of cement. The production of polymer concrete will help in the<br />

reduction of volume of voids in the aggregate. This will hence<br />

reduce the amount of polymer that is necessary to bind the<br />

aggregates used.<br />

Hence the aggregates are graded and mixed accordingly to<br />

achieve minimum voids hence maximum density.<br />

This type of concrete has different categories<br />

11. High-Strength Concrete<br />

the high strength concrete ought to be less performing in terms<br />

of workability which is an issue.<br />

12. High-Performance Concrete<br />

These concretes conform to a particular standard but in no<br />

case, will be limited to strength. It has to be noted that all the<br />

high strength concrete can be high-performance type. But not all<br />

high-performance concrete (HPC) are high strength concrete.<br />

Standards that conform to the high-performance concrete are<br />

enlisted below:<br />

Strength gain in early age<br />

Easy placement of the concrete<br />

13. Self – Consolidated Concrete<br />

The concrete mix when placed will compact by its own weight is<br />

regarded as self-consolidated concrete. No vibration must be<br />

provided for the same separately.<br />

This mix has a higher workability. The slump value will be<br />

between 650 and 750.<br />

This concrete due to its higher workability is also called as<br />

flowing concrete. The areas where there is thick reinforcement,<br />

self – consolidating concrete works best.<br />

14. Shotcrete Concrete<br />

Here the concrete type differs in the way it is applied<br />

on the area to be cast. The concrete is shot into the<br />

frame or the prepared structural formwork with the help<br />

of a nozzle. As the shooting is carried out in a higher<br />

air pressure, the placing and the compaction process<br />

will be occurring at the same time.<br />

15. Pervious Concrete<br />

Pervious or permeable concrete are concrete that are designed<br />

such a way that it allows the water to pass through it. These<br />

types of concrete will have 15 to 20% voids of the volume of the<br />

concrete when they are designed.<br />

The pervious concrete is created by unique mixing process,<br />

performance, application methods etc. These are used in the<br />

construction of pavements and driveways where storm water


16. Vacuum Concrete<br />

Concrete with water content more than required quantity is<br />

poured into the formwork. The excess water is then removed<br />

out with the help of a vacuum pump without waiting for the<br />

concrete to undergo setting.<br />

Hence the concrete structure or the platform will be ready to use<br />

earlier when compared with normal construction technique.<br />

These concretes will attain their 28 days compressive strength<br />

within a period of 10 days and the crushing strength of these<br />

structure is 25 % greater compared with the conventional<br />

concrete types.<br />

17. Pumped Concrete<br />

One of the main property of the concrete used in large mega<br />

construction especially for the high-rise construction is the<br />

conveyance of the concrete to heights. Hence one such<br />

property of concrete to easily pump will result in the design of<br />

pumpable concrete.<br />

The concrete that is used for pumping must be of adequate<br />

workability so that it is easily conveyed through the pipe. The<br />

pipe used will be rigid or a flexible hose that will discharge the<br />

concrete to the desired area.<br />

The concrete used must be fluid in nature with enough fine<br />

material as well as water to fill up the voids. The more the finer<br />

material used, greater will be control achieved on the mix. The<br />

grading of the coarse aggregate used must be continuous in<br />

nature.


18. Stamped Concrete<br />

Stamped concrete is an architectural concrete where realistic<br />

patterns similar to natural stones, granites, and tiles can be<br />

obtained by placing impression of professional stamping pads.<br />

These stamping is carried out on the concrete when it is in its<br />

plastic condition.<br />

Different coloring stains and texture work will finally give a finish<br />

that is very similar to costlier natural stones. A high aesthetic<br />

look can be obtained from a stamped finish economically. This<br />

is used in the construction of driveways, interior floors, and<br />

patios.<br />

19. Limecrete<br />

This is a concrete type in which the cement is replaced by lime.<br />

The main application of this product is in floors, domes as well<br />

as vaults. These unlike cements have many environmental and<br />

health benefits. These products are renewable and easily<br />

cleaned.<br />

20. Asphalt Concrete<br />

Asphalt concrete is a composite material, mixture of aggregates<br />

and asphalts commonly used to surface roads, parking lots,<br />

airports, as well as the core of embankment dams. Asphalt<br />

concrete is also called as asphalt, blacktop or pavement in<br />

North America, and tarmac or bitumen macadam or rolled<br />

asphalt in the United Kingdom and the Republic of Ireland.<br />

21. Roller Compacted Concrete<br />

These are concrete that is placed and compacted with the help<br />

of earth moving equipment like heavy rollers. This concrete is<br />

mainly employed in excavation and filling needs.<br />

These concretes have cement content in lesser amount and<br />

filled for the area necessary. After compaction, these concretes<br />

provide high density and finally cures into a strong monolithic<br />

block.


22.Rapid Strength Concrete<br />

As the name implies these concretes will acquire strength with<br />

few hours after its manufacture. Hence the formwork removal is<br />

made easy and hence the building construction is covered<br />

fastly. These have a wide spread application in the road repairs<br />

as they can be reused after few hours.<br />

23. Glass Concrete<br />

The recycled glass can be used as aggregates in concrete.<br />

Thus, we get a concrete of modern times, the glass concrete.<br />

This concrete will increase the aesthetic appeal of the concrete.<br />

They also provide long-term strength and better thermal<br />

insulation also.
