ABSTRACT
The present trend in concrete technology is towards increasing the strength and durability of concrete to meet the demands of the modern construction world at lower cost. These factors can be achieved in concrete by adding natural or synthetic fibre. In the case of Glass Fibre reinforced Concrete, strength of the concrete is increased, but at higher cost. Hence, research has to be done to provide an alternative use of fiber glass. In the present study, Glass wool fibre is added to the concrete to increase the strength as compared to the conventional concrete at lower cost. The strength parameters of concrete such as compressive strength and tensile strength were studied by varying the percentage of fibre from 0.025% to 0.075% of the weight of concrete.
