Experimental study of compressive behavior of polypropylene-fiber-reinforced and polypropylene-fiber-fabric-reinforced concrete

Waste fiber fabric has already become an important pollutant source of the world's environmental problems. If this waste was added into concrete, could the resulting composite concrete material be good enough for engineering use? This study is focused a feasibility study of the addition of polypropylene fiber fabric into concrete, as well as analysis of its compression property, damage evolution rule, and damage performance in macroscopic and microscopic fields. Concrete specimens were made from polypropylene spun-bonded materials produced from used clothes. Their compressive behavior, energy absorption characteristics, and destruction characteristics were compared with plain concrete (PC) and polypropylene-fiber-reinforced concrete (PPFRC). The result indicate that the addition of waste fiber fabric can improve the compression performance of concrete. The addition of waste fiber fabric materials to concrete is a technology that can be constantly improved, considering changes in both technical and environmental conditions. (C) 2018 Elsevier Ltd.
