Abstract: This project was carried out to understand the effects of glass fibre on concrete. Glass fibres are available at cheaper cost in market. Glass fibre was added as an admixture to know its effects on concrete. To increase the life of structure, Glass Fibre reinforced concrete can be used. It is often known as GFRC. Various percentage of glass fibres were added in concrete and the results were compared with Plain Cement Concrete to understand the Effects of glass fibre on concrete. Concrete beams were casted and allowed to cure for 28 days. The result showed that addition of 1% of glass fire increased the flexural strength of concrete, there were minimal or no changes noted in workability of concrete. On further addition of 2% of glass fibre, although the strength of concrete increased significantly but the workability of concrete decreased. It became very difficult to handle thee concrete and carry out tamping process.

Keywords: Glass fibre, Effects, Flexural strength, Analysis
