Studying the behavior of geopolymer concretes under repeated loadings

Abstract This article investigates utilization of polypropylene microfibers as reinforcement in geopolymer concrete to enhance the ductility characteristics since is considered a brittle material. The were added at fiber volume content 0.5%, 1.0%, and 1.5%. In this article, slump test compressive strength tested for concretes measure effect on concretes. Also, static flexural dynamic loading applied find out attitude fiber-reinforced both deflection number load cycles until failure. While comparing results with reference concrete, all samples 28 days and, finally, statistical was carried out. concluded that use improves enhances properties concretes, increases appearance first crack, decreases compared concrete.
