CONCRETE LIGHT - POSSIBILITIES AND VISIONS 

Manfred Curbach Silke Scheerer 

1 Introduction 

The building material of the century - reinforced concrete - was in the past 100 years the most 

successful building material. This it will remain until further notice in this century. The history of 

this material is well known and often described, e.g. [1]. The invention of a hydraulic binder, the 

"Roman Cement", is often referred to as the first milestone. For this the Briton James Parker 

received a patent in 1796. Mid-19th century several people began independently to insert iron into 

concrete. On behalf of all the Frenchman Coignet should be mentioned. He built the roof of his 

house as a flat, iron-reinforced concrete slab [1]. Other applications followed (Fig. 1) and the study 

of material behaviour has been pushed. Soon, a variety of patents were awarded and construction 

codes and the first standards were written. The composite material reinforced concrete - later 

reinforced concrete - was born and could take up his victory.

One was aware of the significance of this invention well. Therefore, it was thought in the first half 

of the previous century, innovations in construction are no longer possible. Known is, for example, 

the anecdote that Professor Finsterwalder should have advised his son – Ulrich Finsterwalder - 

against studying civil engineering [4]. It should hardly be expected with new inventions, as the 

state of the art is already so high - that was the opinion of a renowned professor at the beginning of 

the 1920s. 

That this view was wrong we know today. To increase the capacity of the conventional 

reinforced concrete, steel was prestressed. Later Ulrich Finsterwalder himself developed together 

with colleagues the still used Dywidag-prestressing method or the cantilever method. With this 

construction method bridges with spans up to 300 m have been built till today [5]. Beside bridges, 

for example, shell structures, whose heyday between 1960 and 1970 was (Fig. 2), also show 

particularly impressive the performance of the reinforced concrete as building material and the 

performance of the different, always new developed Construction methods. In the 1980s, an 

innovation jam started, that lasted until the early 1990s.

In the recent past, the researchers can look back on a number of innovations. On the one hand the 

development of more efficient concretes - the so-called concretes of the new generation - was 

pushed successfully. On the other hand, the search for new type tensile reinforcement materials was 

intensified as the susceptibility to corrosion of conventional reinforcing steel the engineer often 

forces to construct components thicker than would be required static. And just herein was and is 

a major research focus of the Institute of Concrete Structures of the TU Dresden. 

2 The beginning of research on textile reinforced concrete (TRC) 

at the TU Dresden 

The search for alternative material combinations had the goal to open up new design possibilities 

and uses for concrete construction through improved material properties. In the mid-1990s, 

Dresden researchers had the idea to insert textile fabrics of non-corrosive endless filaments with 

a very high tensile strength instead of the corrodible reinforcing steel into concrete, which only has 

a very low tensile strength. 

But the idea of embedding fibres into brittle materials is not new. Already thousands of years 

ago was the straw mixed with clay. The bricks produced from it were then more resistant to 

cracking, for example, due to the large temperature fluctuations during the day [7]. In modern 

times, since the early 1990s fibre concrete has developed as an alternative to steel-reinforced 

normal concrete. In this type of concrete short fibres made of steel, polymer or glass will be added. 

Besides an increase in compressive and tensile strength, the randomly oriented fibres have



especially positive effect on the bending tensile strength. Therefore, fibre-reinforced concrete is 

often used in highly loaded industrial floors. 

The use of endless filaments or of fabrics made of such filaments as a substitute for common 

reinforcement was still a very new approach. Among experts, the new, innovative composite 

material is now well-known as textile reinforced concrete or TRC. After initial experiments (Fig. 3) 

with textiles made from alkali-resistant glass (AR glass) had delivered promising results, 1999, the 

Collaborative Research Centre 528 "Textile Reinforcements for Structural Strengthening and 

Repair" (in short: SFB 528) was launched at TU Dresden [8]. 

Fig. 3 First specimens of textile concrete: window lintels with polystyrene core; right: first experimental 

results 

The newly developed construction material is characterized primarily by its lightness combined 

with high load capacity. Typical component thicknesses are 1-3, in exceptional cases up to 

5 centimetres. The reinforcement is flexible. Thereby curved forms can be realized much easier 

than with reinforced concrete. TRC is suitable for fabrication of new components and for 

strengthening of existing ones. Components strengthened with TRC have a significant higher load 

bearing capacity. At the same time deformations are limited, e.g. deflection of plates or beams. 

Also noteworthy is the characteristic crack pattern of TRC. In contrast to reinforced concrete 

cracks occur in a much smaller distance with very low crack width (Fig. 4). 

The lightness of the innovative composite construction material is not only important in 

terms of its own dead weight. This property also brings effective relief to the construction workers 

in the practical application. Thus, the textile fabric can be cut with scissors and easily applied by 

hand without the use of heavy equipment. The fine grained concrete can be applied, for example, 

with trowel and spatula or with a commercial spraying device.

3 The construction material TRC 

Textile reinforced concrete consists of two components - the textile fabric and a special fine 

grained concrete. In contrast to fibre-reinforced concrete, in which the reinforcing fibres are 

embedded undirected, the TRC is made of fabrics of continuous fibres. Fig. 5 shows a comparison 

between glass and carbon yarns and common reinforcement. The individual yarns are arranged 

oriented in the fabric, whereby the tensile reinforcement can be designed similar to the reinforcing 

steel in reinforced concrete according to the strength flow in the component. A detailed description 

can be found in [9]. Here only briefly the most important terms explained (Fig. 6). 

32 

Fig. 5 Size comparison for reinforcements (from top to bottom): glass roving, carbon roving, reinforcing 

steel (Øs = 14 mm), prestressing strand (A = 15 mm²), [9] 

Fig. 6 Manufacturing of textile reinforced concrete



Basic element of the textile fabric is the single continuous fibre - the so-called filament. For TRC, 

we use AR-glass fibres or carbon fibres. The glass melt is enriched with a certain percentage 

zirconium, which makes the glass insensitive to the alkaline attack in the concrete matrix. The 

diameter of a single AR-glass fibre varies according to the producer between 14 to 28 mm. 

A carbon fibre is with a diameter of about 7 mm significantly thinner [9]. In comparison, a human 

hair is at least up to 120 mm thick [10]. 

The single filaments are combined into fibre bundles - also called multifilament yarns or 

rovings. One roving usually contains several hundred single filaments which lie parallel to each 

other without rotation. Before single AR-glass or carbon filaments are combined into a yarn, the 

sizing is applied. This special chemical solutions effect for example surface improvements of the 

filaments, make the filaments suppler and more resistant against mechanical stress [11]. 

On textile machines, the rovings are processed into textile fabrics. At the TU Dresden 

several textile machines are available. The fabrics can be produced from AR-glass, carbon or 

a combination of both fibre types. The number of yarn layers and the fabric geometry depend on 

the specific application (Fig. 7). 

Fig. 7 Examples for different fabrics; left: carbon fabric with typical dimensions; middle: fabric for shear 

force strengthening; right: fabric for bending strengthening 

For the application of this textile fabrics a special mineral matrix - the so-called fine grained 

concrete - was developed at the Technical University of Dresden. The maximum aggregate size of 

this concrete has typically a diameter of 1 mm. This size resulted from the dimension of the 

reinforcement on the one hand and the intended low layer thicknesses on the other. According to 

common definition such a matrix is classified as a mortar. Due to the mechanical properties of the 

material, however, the term fine grained concrete was chosen. As binder a combination of cement, 

fly ash and microsilica is used. The quantitative ratios and the type of cement depend on the 

intended use of the TRC. In addition to the water plasticizer is still added. 

The mechanical properties of hardened concrete are determined according to DIN EN 1015- 

11:2007-05 T2 (mortar; pressure and bending tensile strength) and according to DIN 1048-5 

(elastic modulus of concrete) on prismatic samples (4 × 4 × 16 cm) respectively. Because of its 

high compressive strength the fine grained concrete can be classified as high-strength concrete. 

Examples for typical mix proportions and resulting mechanical properties are given in Tab. 1. 

TRC can be made in different ways. Basically, so far three methods have been applied: 

• lamination, 

• spraying, 

• injection, 

at which the third variant currently is of secondary importance. When laminating, first one few 

millimetres thick layer of fine concrete is applied to a prepared surface or into a mould. Then 

alternately, previously cut textile fabric and thin layers of fine concrete matrix are placed. The fine 

grained concrete can, for example, be spread with a trowel and smoothed before the next layer of 

33



fabric carefully placed and lightly pressed into the fresh matrix. Least the final layer of fine 

concrete is smoothed. The manufacture of TRC by spraying differs from laminating only in the 

way of concrete applying (Fig. 8). This is no longer made by hand but with the help of a spraying 

device, such as those used when applying render. The concrete curing is similar to conventional 

concrete.

In the case of strengthening the ground must be carefully prepared. First, by sandblasting the 

surface is roughened. After the removal of dust or loose concrete particles the ground is moistened. 

Now, with the application of fine concrete matrix can be started. 

4 Experimental researches 

Before a new building material can be used in practice, it has to prove itself in experiments. The 

material behaviour must be explored and described. Calculation methods must be developed. Some



research results are presented here in brief. The focus of our research is the use of textile concrete 

to increase load bearing capacity of existing reinforced concrete structures. The most common 

loading scenarios are bending, shear and torsion or exposure to normal forces. 

Fig. 9 4-point bending tests on a strengthened slab (Photo: Silvio Weiland) 

Fig. 10 Comparison of different fabrics for flexural strengthening of reinforced concrete slabs [12] 

For components with insufficient bending bearing capacity TRC is applied in the tensile zone. The 

fine grained concrete layers are just a few millimetres thick. The total thickness of the TRC layer is 

thus dependent on the number of textile layers. The potential of strengthening with TRC could be 

impressively demonstrated in numerous experiments. The experimental setup is shown in Fig. 9. At 

this single-span ceiling panels, the TRC layer at the bottom of the component is applied. The 

reinforcement layer ends before the supports. Exemplary results are shown in Fig. 10. In the 

35



illustrated test results the number of textile layers and the type of the fibres and fabrics were varied. 

The load carrying capacity could be increased up to twice the reference plate in three cases. The 

significantly more rigid behaviour of the strengthened plates at identical loads is also remarkable, 

which is interesting especially for changes of use of buildings and in terms of the deflection 

restrictions. 

At ceiling panels are mainly the bending bearing capacity and the deflections positively 

impacted by a TRC strengthening. At beams and T-beams is often the shear capacity critical, 

especially in buildings from the early days of reinforced concrete construction. The inclination of 

the AR-glass fibres in the main load direction of the fabric is adapted in the direction of the 

principal stresses in the web with an angle of ±45° ([13] and Fig. 11). The particular difficulty at 

such components is the anchoring of the textile reinforcement. Especially at T-beam the pressure 

zone is generally not accessible to the strengthening works. 

36

Fig. 12 Test set up for torsion tests [15]



Torsion is relevant for example for edge beams, electricity pylons etc. Therefore, rod-shaped 

reinforced concrete components have been strengthened with TRC and investigated experimentally 

in torsion tests. The experimental setup is shown in Fig. 12, exemplary test results in Fig. 13. 

Fig. 13 Exemplary results from torsion tests on specimen with circular cross section [15] 

Also as subsequent reinforcement of columns, textile reinforced concrete has proven [16]. For 

example, at 2 m high columns load increases between 35 % and 66 % were obtained even with two 

AR-glass fabric layers, depending on the kind of textile. In the recent past, compression tests were 

made on large-sized columns in a new 10-MN testing machine, (Fig. 14, [17] and [18]). 

Fig. 14 Experiments on large-scale columns; left: experimental setup; Middle: reinforced concrete columns 

with and without reinforcing carbon fabric after the test; right: fine, evenly distributed cracks by 

a strengthened column (Photos: Christian Dittrich and Ulrich van Stipriaan) 

37



An unstrengthened reference column of common reinforced concrete and two, with 5 layers of 

carbon fabric reinforced components were examined. As expected, the load bearing capacity of the 

strengthened columns could be significantly increased to almost the double value compared to the 

reference column. Impressively, however, was especially the much more ductile failure 

mechanism. Strengthening with carbon fabric and fine concrete caused, that many fine cracks 

distributed over the circumference and the height of the column before the maximum load was 

reached and failure occurred. At the purely reinforced concrete column the damage focused on the 

upper part of the component. The prescribed effects are documented also in Fig. 14. 

5 Practical applications of textile reinforced concrete 

5.1 Strengthening of components 

Without the built environment is our life today would be unthinkable. Habitation, employment, 

transport, utilities - everything that is impossible without buildings or roads. Nevertheless the 

building stock must be maintained and preserved as a permanent new building would be neither 

financially feasible nor environmentally acceptable. Environmental influences or modified load 

scenarios can cause, that an existing construction a loading can not longer withstand safely. In 

bridge building play, for example, the increased traffic and higher axle loads a role. Therefore, our 

focus is on practical application of TRC in light, stable strengthening of existing elements. A few 

outstanding examples are introduced below. 

The first major project was the increase of the load bearing capacity of a hypar shell over the 

"big lecture hall” at FH Schweinfurt revisited [19]. The already built in the 1960s reinforced 

concrete shell has a maximum span of about 39 m and in many areas this thickness of the shell is 

only 8 cm. This structure had to be urgently repaired and the load bearing capacity had to be 

upgraded. In this project could be demonstrated for the first time the impressive benefits of the 

TRC in its practical application. In addition, the application of TRC was finally the only 

reinforcement method that could be realized in this building project. Neither the partly substantial 

roof pitch nor the expected high temperatures on the roof top represented a problem. Moreover, the 

2-dimensional TRC layer allows the dissipation of differently oriented forces into the shell. 

As expected, the processing of the building material was found be uncomplicated - and the 

layer thickness of 1.5 cm represented only a very small increase in dead weight of the roof 

structure. As a comparison, the usual thickness of shotcrete is 8 cm. In several steps alternating fine 

concrete layers and three layers of carbon fabric were applied within a few days on the whole roof. 

Meanwhile, the Institutes staff was permanently on site to advise and monitor the work itself and 

the concrete curing. An impression of the construction work provides Fig. 8. 

38 

Fig. 15 Cross section of the roof structure to be strengthened [20]



In Zwickau a landmarked barrel-vault from the early days of reinforced concrete should be 

preserved [20]. At this historic building (built in 1903) the demands made by the planner, the 

preservationists and the users were high. Above all, the geometry of the shell should be largely 

preserved. Fig. 15 shows a cross section through the 8 cm thick, corrugated reinforced concrete 

slab with a rectangular window openings and one of the eleven beams that are connected to the 

plate monolithic. As at the project in Schweinfurt, with none of the conventional methods could all 

the conditions are fulfilled. Only TRC came into consideration. 

Once the existing plaster had been removed, the surface of the old concrete was roughened 

by sand blasting. In addition, existing defects were repaired. Thereafter, the surface was wetted and 

the first layer of fine concrete was sprayed. Subsequently, the previously cut textile fabric made of 

carbon yarns was embedded into the fresh fine grained concrete. Successively, all of the five static 

required reinforcement layers have been applied. As a final layer were again sprayed 3 mm fine 

concrete. The thickness of the strengthening layer was again with a total of 1.5 cm extraordinarily 

low. Finally, there was a seven-day concrete curing to prevent shrinkage cracks. The various steps 

are illustrated in Fig. 16. 

But the use of textile reinforced concrete for strengthening is not limited to those special 

constructions described above. This shows a construction project from 2009. In a multi-storey 

commercial building had to be strengthened more than 2200 m² of the ceiling. The bending load 

capacity had not been sufficient. Strengthening with shotcrete or CFRP plates had to be excluded 

for constructive and technical reasons. Therefore, the structural safety has been restored with 

a layer of textile reinforced concrete.

5.2 New components 

TRC is not only a "lightweight" strengthening method. “Concrete light” is also possible at new 

components or structures. Outstanding examples are two segmental bridges made of textile 

reinforced concrete, which were built under the leadership of the Institute of Concrete Structures. 

The world's first textile reinforced concrete bridge was built for the National Garden Festival 

in 2006 over the Döllnitz in Oschatz (Saxony). The lightweight, innovative bridge construction 

convinced the scientific community - and was awarded: in 2006 with the "Special Encouragement 

Award" of the Fédération Internationale du béton (fib) and in 2007 with the “Innovation Award of 

the concrete components supply industry”. In the fall of 2007, a second, 17 m long foot and cycle 

bridge in Kempten (Allgäu) was opened to the public [22]. The 18 u-shaped elements of the 

sweeping bridge over the Rottach were prepared by spraying method at the precast plant in 

Oschatz. 

Fig. 18 shows the cross-section of the bridge in Oschatz. The reinforcement of the elements 

consisted mainly of AR-glass fabric, arranged in four layers. The only 3 cm thick TRC-shell is 

footway, railing and supporting structure all in one. Longitudinal stiffeners, stiff transversal rib on 

the element edges and enlargements of cross section in the areas of the handrails and at the bottom 

corners give the slender shell shape stability (Fig. 17). 

Fig. 17 Cross-section of the TRC bridge in Oschatz [22] 

After completion of all individual segments (Fig. 18), the single elements were aligned on 

a falsework and checked for fitting accuracy. Then, the individual segments were glued together 

step by step. By temporarily clamping together the all-over filling of the joints was guaranteed.



After all of the individual segments were connected, the bridge was longitudinally prestressed by 

monostrands. The entire bridge could be transported to their location as special transport. The 

bridge today shows Fig. 19. 

Fig. 18 Prefabricated elements before clamping together [22]

But not only light bridges can be realized in textile reinforced concrete. Another promising future 

field of applications are wall panels from TRC. Our institute is cooperating closely with industry 

partners to achieve easy and economical solutions. Conventional reinforced concrete facades are 

very massive because of the corrosion protection of steel reinforcement this is necessary. Due to 

the high dead load extensive anchoring systems are required [22]. 

Taking into account also the needs of thermal protection, there are usually high layer 

thicknesses, which makes conventional, prefabricated wall panels unattractive in many cases. 

41



A promising alternative are the thin-wall TRC panels of Hering Bau GmbH & Co. KG (Fig. 20). In 

addition to use for covering new buildings, the system is due to its low dead weight suitable 

particular in the improvement in building stock [22]. Also, an anchor in less stable ground is 

possible. 

6 Outlook

Concrete and light weight - TRC is a way to resolve this apparent contradiction. 

Textile reinforced concrete stands for: 

• Innovation, 

• Light weight constructions, 

• Flexibility, 

• Unconventional shape and 

• Unusual solutions. 

TRC has potential for building maintenance, as well as new construction.

After 12 years of intensive research funding of the SFB 528 by the German Research Foundation 

(DFG) in summer will end. The research activities of the SFB 528 are now being continued 

especially in practically oriented projects and in the Deutsches Zentrum für Textilbeton (DZT) 

[23]. Research and application of TRC will continue to be a research priority at the Institute of 

Concrete Structures of the TU Dresden, even after termination of the SFB 528. Already, more 

interesting projects are planned, e.g. a new bridge for pedestrians and cyclists (Fig. 21). 

We will also pursue other approaches to advance the lightweight construction with concrete. 

With particular interest we will pursue the results of the DFG priority program "Concrete light. 

Future concrete structures using bionic, mathematical and engineering formfinding principles”, its 

coordination is our responsibility. The aim of this interdisciplinary program is to initiate 

a paradigm change in construction: towards the light building with concrete away from the solid 

building as a standard in the "ordinary" building, not just as a special solution in leading individual 

projects.
