AN EXPERIMENTAL STUDY ON RICE HUSK ASH AND GLASS FIBER REINFORCED CONCRETE

Abstract

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 Rice Husk ash, fly ash,
silica fume, etc. as partial replacement of cement. The composite matrix that is obtained by combining cement,
Rice Husk ash, aggregates and fibers is known as “Rice Husk ash Fiber reinforced concrete”. The fiber in the
cement Rice Husk ash 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 (by weight) with (5%, 10%, 15%) Rice Husk ash and the effects of addition of (0.5%,
1%, 1.5%) Glass Fiber composite. A M30 Grade of concrete control mixture of prop ortions 1:1.91:3 with w/c
of 0.50 was designed. This study reports the feasibility of use of Glass fibers and Rice Husk ash content on
structural properties such as compressive strength, split tensile strength, and flexural strength test
