Abstract

This research work investigates the effect of the addition of nylon and polypropylene fibers on the mechanical properties of concrete. Straight nylon fibers (ST) with a 63mm length and 0.9 mm diameter, and Polypropylene fibers (PP) with a 6mm to 12 mm and diameter 30-45 microns were used. Each type separate and three mixtures were produced with the combination of nylon and polypropylene fibers in addition with nano silica. Compressive strength and flexural strength tests were performed and results were analyzed to associate with above fiber combinations. Based on experimental studies, the paper identifies fiber combinations that demonstrate maximum compressive and flexural strength of concrete. Relationship between compressive strength and flexural strength is presented. Among different combinations of nylon and polypropylene fibers with and without addition of nano silica investigated. Finally, the results show that introducing fibers to concrete resulted in increase in Compressive strength and flexural strength and depending on the fibers ratio used, compared to the mixture of nominal concrete.
