“…Considering the large surfaces targeted by the retrofitting interventions, a primary objective is to avoid material wastage; in this sense, there is a major need of guidelines and simplified predictive models that can effectively assist the identification of optimum design solutions. Being the tensile behaviour of TRC strongly influenced by the matrix composition [7,8], the geometrical and chemo-mechanical characteristic of the embedded fabrics [9][10][11] and the possible presence of short Bending and compressive tests were carried out on six nominally identical prismatic specimens (40 × 40 × 160 mm 3 ) according to UNI EN 196 [18] and the tensile strengths f ct were deduced from the bending results via the formula proposed in the Model Code 2010 (MC2010) [19]:…”

Textile reinforced concrete (TRC) is a promising high-performance material that has been employed with success in new constructions, as well as a strengthening layer of existing structural components. In this work, we document the optimisation procedure of textile-based composites for new construction and for the seismic retrofitting of under-reinforced concrete elements and masonry buildings. The study, aimed at maximising the material performances avoiding waste of economic resources, was addressed by means of a series of uniaxial tensile tests conducted on a wide set of alkali-resistant (AR) glass fabrics and TRCs. The samples differed in terms of cement-based matrices, embedded textiles and addition of dispersed microfibers. The results highlight the effects of fabric characteristics and introduction of short fibres on the mechanical behaviour, proposing novel comparison parameters based upon the load bearing capacity and the deformation response of the composites. The application of simplified analytical models borrowed from the literature finally revealed the limitations of the available predictive approaches, suggesting future lines of investigation.

Textile reinforced concrete, especially textile reinforced concrete with carbon fibres, was already been used for strengthening steel reinforced concrete structures under static loads up to now. The question is if the composite can also be used for strengthening structures against impact loads. The main goal of a current research project at the Technische Universität Dresden is the development and characterization of a reinforcement fabric with optimized impact resistance. But there is a challenge. There is the need to find the best combination of fibre material (glass, carbon, steel, basalt, …) and reinforcement structure (short fibres, 2D-fabrics, 3D-fabrics, …), but testing the large number of possible combinations is not possible with the established methods. In general, large-scale tests are necessary which are very expensive and time consuming. Therefore, a new testing method has been developed to deal with this large number of possible combinations of material and structural experiments. The following paper describes this new testing method to find the best fabric reinforcement for strengthening reinforced concrete structures against impact loads. The testing devise, which is located in the drop tower facility at the Otto Mohr Laboratory, and the test set-up are illustrated and described. The measurement equipment and the methods to evaluate the experimental results are explained in detail.

“…To guarantee a good workability of the concrete, several concrete mixtures were developed in the past. A good overview is given in study of Mechtcherine et al, and detailed information can be found, for example, in study of Brockmann .

The goal of the common research project autartec, funded by the German Federal Ministry of Education and Research (BMBF), is the development of a modular system for largely self-sufficient buildings. Specifically, known technologies, for example, for solar power and heat generation or decentralized storage should be developed so that they can be integrated space saving into the building envelope or the building structure of energetically and climatically functional buildings. Within the frame of Joint project I "Functionally integrated components made of textile concrete," lightweight elements for stairs and walls were developed. For these applications, carbon reinforced concrete provides new possibilities in the design of high performance space saving construction components. The innovative wall elements will be introduced in this article. K E Y W O R D Sautarkic housing, carbon reinforced concrete, wall elements
