Effects of Glass Fibre on the Strength and Properties of Concrete

Abstract

In the modern world, people are building very complicated civil engineering buildings. As the most important and commonly used material, concrete is often asked to have very high strength and enough workability. In the area of concrete technology, people are trying to make these kinds of concrete with unique properties. This study investigates the possibility of using glass fibre at different percentages as a partial replacement of fine aggregate. The procedure was followed as per the BS EN requirements. There did not seem to be a drastic change in the compressive strength as compared to the M30 grade concrete. The results of these factors are compared to those of standard C30-grade concrete. The flexural strength increased as the amount of glass fibre increased. The slump value decreased as the amount of glass fibre increased. Thus, a lower percentage of glass fibre would be an appropriate solution to deal with major parameters of concrete like compressive strength, flexural strength, and workability. The utilisation of the waste glass fibre in concrete would be a good option to some extent and a way for a sustainable approach.
