Abstract
Concrete has become basic material in day to day life of humans. In recent years lot of research is going on the development of high strength concrete by using supplementary materials for cement and aggregates. The present investigation is mainly focused on the effect of mechanical properties and durability of high strength concrete with supplementary materials. In this investigation concrete having compressive strength M30 with rice husk ash (RHA) as supplementary material. Rice husk added to the concrete with 0 to 20 % by weight of cement. Sulphuric Acid (H2SO4) and Hydrochloric acid (HCl) has been used as curing media in this investigation apart from the water. Fresh properties of concrete like slump and hardened properties like compressive strength, split tensile, flexural strength after 7 and 28 days of curing are conducted along with durability. The results show that FA and RHA can be used as supplementary cementitious material with optimum dosages.
