AN EXPERIMENTAL STUDY ON GLASS FIBER REINFORCED CONCRETE USING RICEHUSK ASH AS PARTIAL REPLACEMENT IN CEMENT

The infrastructure needs of our country is increasing day by day and with concrete is a main constituent of construction material in a significant portion of this infra-structural system. It is necessary to enhance its characteristics by means of strength and durability. It is also reasonable to compensate concrete in the form of using waste materials and saves in cost by the use of admixtures such as byproducts, fly ash, silica fume, etc. as partial replacement of cement. The composite matrix that is obtained by combining cement, byproducts, aggregates and fibers is known as “By products Fiber reinforced concrete”. The fiber in the cement byproducts-based matrix acts as crack- arresters, which restrict the growth of micro cracks and prevent these from enlarging under load. The experimental work has carried out to study the effects of replacement of cement rice husk ash(by weight) with (5%, 10%, 15%,20%). By products and the effects of addition of (0.5%, 1%, 1.5%) Glass Fiber composite. A M40 Grade of concrete is designed. This study reports the feasibility of use of Glass fibers, by products, super plasticizers, air entraining agents and accelerators content on structural properties such as compressive strength, split tensile strength, and flexural strength test.
