Lakhan Nagpal, Arvind Dewangan, Er. Sandeep Dhiman, Er. Sumit KumarAbstract -- The purpose of this study was to investigate thepossibility of using crushed stone dust as fine aggregate partiallyor fully with different grades of concrete composites. Thesuitability of crushed stone dust waste as fine aggregate forconcrete has been assessed by comparing its basic properties withthat of conventional concrete. Two basic mixes were selected fornatural sand to achieve M25 and M30 grade concrete. Theequivalent mixes were obtained by replacing natural sand bystone dust partially and fully. The test result indicates thatcrushed stone dust waste can be used effectively used to replacenatural sand in concrete. In the experimental study of strengthcharacteristics of concrete using crushed stone dust as fineaggregate it is found that there is increase in compressivestrength , flexural strength and tensile strength of concrete.Keywords: concrete, strength, fine aggregate, crushed stone dust.I. INTRODUCTIONConventionally concrete is mixture of cement, sand andaggregate. Properties of aggregate affect the durability andperformance of concrete, so fine aggregate is an essentialcomponent of concrete. The most commonly used fineaggregate is natural river or pit sand. Fine and coarseaggregate constitute about 75% of total volume. It istherefore, important to obtain right type and good qualityaggregate at site, because the aggregate form the mainmatrix of concrete or mortar.The global consumption of natural sand is very high, due tothe extensive use of concrete. In general, the demand ofnatural sand is quite high in developing countries to satisfythe rapid infrastructural growth, in this situation developingcountry like India facing shortage in good quality naturalsand. Particularly in India, natural sand deposits are beingdepleted and causing serious threat to environment as wellas the society. Increasing extraction of natural sand fromriver beds causing many problems, loosing water retainingsand strata, deepening of the river courses and causing bankslides, loss of vegetation on the bank of rivers, exposing theintake well of water supply schemes, disturbs the aquaticlife as well as affecting agriculture due to lowering theunderground water table etc are few examples.In past decade variable cost of natural sand used as fineaggregate in concrete increased the cost of construction. Inthis situation research began for inexpensive and easilyavailable alternative material to natural sand.Manuscript received on May, 2013.Er. Lakhan Nagpal, A.P.-S.B.

Sumit Kumar, A.P.-Gateway Institute of Engineering andTechnology,Sonipat,Haryana, India.Some alternatives materials have already been used as a partof natural sand e.g. flyash, slag limestone and siliceousstone powder were used in concrete mixtures as a partialreplacement of natural sand.However, scarcity in required quality is the major limitationin some of the above materials. Now a day’s sustainableinfrastructural growth demands the alternative material thatshould satisfy technical requisites of fine aggregate as wellas it should be available abundantly.II. LITERATURE REVIEWCommon river sand is expensive due to excessive cost oftransportation from natural sources. Also large-scaledepletion of these sources creates environmental problems.As environmental transportation and other constraints makethe availability and use of river sand less attractive, asubstitute or replacement product for concrete industryneeds to be found. River sand is most commonly used fineaggregate in the production of concrete poses the problem ofacute shortage in many areas. Whose continued use hasstarted posing serious problems with respect to itsavailability, cost and environmental impact?Materials And MethodsCementOrdinary Portland Cement (43 Grade) with 28 percentnormal consistency Conforming to IS: 8112-1989 [3] wasused.Quarry rock dustThe Quarry Rock Dust obtained from local resource AMCCrushers (P) Ltd., Dindigul was used in concrete to cast testcubes and beams. The physical and chemical properties ofQuarry Rock Dust obtained by testing the samples as perIndian Standards are listed in Tables 1 and 2, respectively.Fine aggregate (Natural river sand)River sand having density of 1460 kg/m 3 and finenessModulus (FM) of 2.51 was used. The specific gravity wasfound to be 2.6.Coarse aggregateNatural granite aggregate having density of 2700kg/m 3 andfineness modules (FM) of 6.80 was used. The specificgravity was found to be 2.60 and water absorption as 0.45%.AdmixtureCommercially available Super-plasticiser has been used toenhance the workability of fresh concrete for selectedproportions of ingredients.Mix DesignSince there is No standard method of designing concretemixes incorporating Quarry Rock Dust as fine Aggregate.The method mix design proposed by IS, ACI, USBR, RNNo.4, BS were first employed to design the ConventionalConcrete mixes and finally natural sand was fully replacedby Quarry Rock Dust to obtain Quarry Rock Dust concretemixes. The purpose of mix proportioning is to produce the102

Evaluation of Strength Characteristics of Concrete Using Crushed Stone Dust as Fine Aggregaterequired properties in both plastic and hardened concrete byworking out a combination of available materials, withvarious economic and practical standards.III. RESEARCH SIGNIFICANCEBased on the above discussions, following conclusions aredrawn:(a) The Physical and chemical properties of quarry rock dustis satisfied the requirements of code provision in propertiesstudies Natural river sand, if replaced by hundred percentQuarry Rock Dust from quarries, may sometimes give equalor better than the reference concrete made with NaturalSand, in terms of compressive and flexural strength studies(b) Studies reported here and elsewhere have shown that thestrength of Quarry Rock Dust concrete is comparatively 10-12 percent more than that of similar mix of ConventionalConcrete. Also the result of this investigation shows thatdrying shrinkage strains of Quarry Rock Dust concrete arequite large to the shrinkage strain of Conventional Concrete.However, at the later age, they have shown equal strain thanConventional Concrete. The Durability of Quarry Rock Dustconcrete under sulphate and acid action is higher inferior tothe Conventional. Permeability Test results clearlydemonstrates that the permeability of Quarry Rock Dustconcrete is less compared to that of conventional concrete.The water absorption of Quarry Rock Dust concrete isslightly higher than Conventional Concrete. Therefore, theresults of this study provide a strong support for the use ofQuarry Rock Dust as fine aggregate in ConcreteManufacturing.IV.REFERENCES[1]. Prakash Rao D.S. and Gridhar V. 2004.
