Abstract
The study describes an experimental study into the relationship among incorporation of Glass Fiber on the fresh and hardened properties of concrete. The effect of fiber fractions on the slump, compressive strength, splitting tensile strength and flexural strength of Glass Fiber Reinforced Concrete (GFRC) were investigated for volume fraction (VF) of 0%, 1%, 2% and 4%. In order to serve the purpose, concrete cylindrical and prism specimens were made with various rates of fiber-glass polymer. The cylinder specimens were tested at 7 and 28 days for compressive strength and at 28 days for splitting tensile strength, whereas the prism specimens were tested at 28 days for flexural strength. The experimental test results show that the additions of glass fiber polymer to concrete decrease slump, but increase compressive strength, splitting tensile strength and flexural strength. In addition, an analytical model has been proposed to predict slump of fresh concrete.
