Experimental Study on Physio-mechanical behavior of Concrete with Chopped Fiberglass Strands
Abstract
In building construction, use of fiberglass in concrete is gradually increasing after following recent trends. Crack developed on plain concrete is certainly reduced and increased the bending and flexural capacity of concrete. This study investigated chopped fiberglass as an additive ingredient of concrete as certain percentage variation of dimension of beam size and impacts of fiberglass on bending performance of concrete beam. The main aim of the study is to study the effect of glass fiber in the concrete. The addition of glass fibers into concrete dramatically increased the flexural strength of concrete. Fiberglass strands were mixed with ordinary concrete as same ratio as per design mix. In this research, 7, 14 and 28-days test was conducted to determine the mechanical strength of concrete, and each test contains three specimens of various six dosage (0%, 0.12%,0.25%,0.5%, 1% and 2%) by weight of total basic concrete ingredients of fiberglass. Here, 54 Numbers of 100 mm x 100 mm x 500 mm rectangular concrete beam were casted then flexural strength of concrete was evaluated, and 54 Numbers of 150 mm x 150 mm x 150 mm concrete cube were casted then test was conducted to evaluate compressive strength and water absorption of concrete. At the 0.25% of fiberglass content in concrete provides the best result in flexure and compression out of fiberglass content concrete. The experiment aims to demonstrate that use of fiberglass in certain percentage may enhances the flexural strength and compressive strength of concrete and cure respectively than that of ordinary concrete cube and beam. Fiberglass may be one of the alternative construction materials to increase performance of concrete where flexural strength required is more than compressive strength.
