Tensile behavior of basalt textile-reinforced mortar (BTRM)

This research aims to evaluate the tensile properties of basalt textile-reinforced mortar. The tension test was carried out on nineteen sets of pin action specimens. The variables studied in the current research are textile mesh size, number of plies, and mortar type, as well as coating some of the textiles with epoxy. The results indicated that increasing the number of plies resulted in an increase in the ductility and the ultimate load of specimens. The polymer modified cementitious mortar reinforced with glass fibers is the most efficient in enhancing the strength and ductility among the different types of mortars used in the study. Moreover, coating textiles with epoxy enhanced the ultimate load by about 25% compared to the uncoated specimens. The experimental results were compared with the corresponding values predicted by a model reported in the literature. The experimental results were in good agreement with those predicted using the model. (C) 2021 THE AUTHORS. Published by Elsevier BV on behalf of Faculty of Engineering, Ain Shams University.
