An Experimental Investigation on Mechanical Properties of Mixed Synthetic Fiber Reinforced Concrete

Abstract

There is a tremendous demand for concrete which is highly workable and durable. Plain cement concrete is weak in tension and there is no minimum resistance to cracking in tension one. In order to overcome deficiencies in concrete to increase performance of concrete fibers were added. This project aims to study the synthetic fibers consisting of three different fiber combinations i.e. Polypropylene, HDPE, Recorn 3s. In this study the mechanical properties of concrete containing fiber were studied including workability of fresh concrete. The addition of synthetic fibers in concrete is by 0%, 0.25%, 0.5%, 0.75%, and 1% by volume of cement. These fibers are used in concrete to increase strength of the reinforced concrete.

In present work, an attempt is made to see effects of fibers on mechanical properties of concrete for 3 days, 7 days and 28 days and is compared with the strengths of nominal mix concrete of grade M40 with percentage variation along with orientation in plain concrete.
