The effect of twisted polymer fibers on the physical and mechanical properties of C35 concrete

Concrete as the most used material, is known as an integral part of construction. So far, many studies have been done in the field of improving the quality of concrete that most of them have examined change in concrete mix design; however, the use of additives and also replacing commonly used materials in concrete with new materials always has been considered. Today, different fibers, especially Forta fibers, are used. In this study, experiments on Forta fiber- reinforced concrete are described. The concrete mixing design and Forta fiber properties are also briefly described. The comparison between the results of the tests showed that Forta fiber- reinforced concretes have more bending strength and modulus of elasticity than normal and ordinary concretes.
