Abstract

New class of building materials which are also known as ‘textile reinforced cementitious (TRC) materials’ offer superior mechanical properties under different loadings like tension and compression. With the increase in applications, TRCs have gained scientists attention for exploring its future possibilities. Therefore, the mechanical characterization for basic mechanical properties is continuously going-on for past few decades. This paper investigates, the pullout response of alkali-resistant glass: AR glass (in two forms i.e. single yarn and textile) from cement matrix under extreme conditions. These conditions are varying pullout velocities (from quasi-static to dynamic loading) at four temperatures from −25 °C to 50 °C. The pullout tests are performed on two mechanical setups (i) an electro-mechanical load frame (for static loading at 5 × 10 m/s) and (ii) drop weight impact test set-up (for dynamic loading at four velocities from 1 to 4 m/s). The testing results are calculated and compared with quasi-static loading results for peak pullout load and work done in fracturing the samples under different loading rates and temperatures. The testing and comparative results highlighted the significant variation in mechanical properties for cementitious concretes (single yarn and textile based). In addition, the analysis of mechanical properties also revealed that at a constant velocity with temperature variations play an important role (variation in bonding performance) which cannot be neglected for using these materials in extreme environmental conditions. However, the displacement at peak force point and failure morphologies (i.e. FESEM scanning of fractured surface) does not show any remarkable variations at different loading velocities and temperatures. Overall, the pullout properties of textile reinforced samples are higher than those of single-yarn reinforced ones. Whereas, the bond-strength of textile reinforced samples is lower than that of single-yarn reinforced ones.
