AN EXPERIMENTAL STUDY STRENGTH PROPERTIES OF GLASS FIBRE REINFORCED CONCRETE WITH PARTIAL REPLACEMENT OF CEMENT WITH SILICA FUME

Since advent of civilization various types of cementitous materials have been used for construction practices. The advent of Ordinary Portland Cement (OPC) recast the construction activities completely. From olden days concrete endure from below tensile strength, limited ductility and small defiance to cracking. To overcome these weaknesses a new variety of concrete is desired. Therefore here is an experimental study proposing changes to the conventional concrete to increase fire resistance, increase crack resistance, increase ductility and flexural strength by partial pinch hitter of silica fume to the cement and introducing fibers in the preparation of the concrete for M30 grade of concrete. In this connection an experimental in-visitation was carried out to descry the compressive, split tensile and flexural strengths with the use of glass fibres and Silica fume in concrete. The glass fibres were added by 0.5%,1.0%,1.5% and 2.0% by volume and cement was supplant by Silica fume in three different percentages of 5%,7.5%,10%,12.5%,15% and 17.5%.by weight of cement..Glass fibre Reinforced Concrete (GFRC) is tested for Compression, Split tensile and flexural strengths. Therefore The results of this study indicates the improving of compressive strength ,flexural strength and Split tensile strength exhibited the highest enhancement with 10% to 15% silica fume replacement and glass fibres at 1% respectively.
