Experimental Investigation on Mechanical and Durable Properties of Glass Fibre by Partial Replacement of cement with Flyash and Silicafume

GFRC has many advantages such as light weight material, steel reinforcement corrosion free and structural deterioration free. So due to these reason the researches all over the world are attempting to develop high performance concrete with the use of glass fiber as well as mineral admixture. The combination of fly ash, alkaline liquids, fine, coarse aggregate and glass fiber resulted in the product called as glass fiber reinforced concrete. In the present investigation glass fiber at different percentages like 0.1%, 0.2% and 0.3% to the volume of concrete were used. And cement was partially replacement by fly ash and silica fume. A 15% of both silica fume and fly ash were used throughout the experiment work. The results of these parameters were compared to those of standard M30 grade concrete. For 0.2% of glass fiber addition with 15% of fly ash and 15% silica fume as cement replacement the maximum strength obtained for both compressive test and split tensile strength test. The specimens were tested for 3, 7, 28, 56 and 90 days. The water absorption test was conducted and the tests were noted. The result specifies that the specimens have an absorption less than 15%.
