Experimental Investigation on Two Way RC Slabs with Textile Reinforced Mortar

Textile-reinforced mortar (TRM) is a cement-based composite material that consists of high-strength fibers in the form of textiles combined with inorganic matrices, such as cement-based mortars. The application of textile-reinforced mortar (TRM) as a means of increasing the flexural capacity of two-way reinforced concrete (RC) slabs is experimentally investigated in this study. In this paper, the effectiveness of textile-reinforced mortars (TRMs), the strengthening configuration on the basis of different orientation and the role of initial cracking in the slab is to be investigated experimentally. Here, a new type of textile (nylon-based textile) is used as strengthening material. Also Polymer-modified cementitious mortars were used as binding material for the textile sheets. For this purpose three large scale RC slabs were casted and tested under point loading in loading frame equipment. It is concluded that TRM increases the cracking load and hence the flexural capacity of two-way RC slabs, also the strengthening configuration plays an important role in the effectiveness of the technique.
