Bonding Performance of Textile Reinforced Concrete

Abstract

Non-woven Polypropylene Textile Reinforced Concrete (PP TRC) can be used as thin coverage layer in concrete structures to decrease significantly the water and sulphate penetration to a structure and eliminate build-up. Despite this fact, the use of PP TRC coverage as mechanical protective surface has never been clearly understood and tested. In this thesis, a double layer of Non-Woven PP TRC has been used and tested on concrete samples, which were subjected to the compressive and tensile tests. Using the experimental data, further mathematical calculation has been provided to support the main task of this report, which was mechanical protection of a load-bearing structure. The result of this investigation revealed that textile reinforced concrete increases the stiffness of composite structure in both tension and compression, although the main problem occurs in the bond between the TRC protective cover and the already existing concrete structure. This bond was described in details based on laboratory data with the help of stress-strain diagrams. It was found out that the bond should be modified in order to increase the performance of the composite action
