Abstract

Concrete is a brittle material with very low tensile unit deformation capacity and tensile strength. Where these properties of concrete are required, by the addition of high-tech fibers produced from different materials within the concrete, weak properties of concrete are being tried to be improved. In this study, it is aimed to investigate the physical and mechanical properties of concretes obtained by using different fibers at %1, 2 and 3 ratios by keeping amount of cement constant in the concrete mixtures. According to experimental results, it was seen that the increasing fiber additive in the concrete mixtures, flexural strength were increased by addition of fibers to concrete, slump and compressive strength were decreased. In addition, unit weights decreased and thermal insulation properties increased positively.
