Mechanical Properties of Geopolymer Concrete Reinforced with the Natural and Waste Plastic Fibers

Abstract

The flexural and splitting tensile strength were investigated on the specimens prepared with the geopolymer concrete (GPC) reinforced by the combined usage of coir and metalized plastic fibers. The combined addition of natural and artificial fibers has not been explored extensively into the GPC. The objective was to obtain the optimum combined dosage of the artificial and natural fibers to prepare a sustainable construction composite. The results showed excellent improvement of the properties of the GPC at the combined addition of 1% of the fibers for all test conditions.
