An Expermental Study on Partial Replacement of Cement with Ricehusk Ash and Glass Fibers

Abstract

Concrete is the main component increase day by day infrastructural needs it is necessary to
enhance its properties such as strength and durability. It would be reasonable to compensate concrete by
using agro and industrial wastes which will decrease the cost and weight of construction. The composite
mixture that is obtained by mixing cement, rice husk ash(RHA) and glass fibres (GF)are called as rice husk
ash fibre reinforced concrete. The primary work was carried out to check the effects of restoring of cement
with RHA by weight at (5%, 10%, 15%) and with addition of glass fibres at (0.5%, 1%, 1.5%) . w/c ratio of
0.45 was adopted. The study reports the results obtained for reinstatement of rice husk ash and glass fibres
by weight of cement and tested for tensile strength and compressive strength at 14 days and 28 days
