Abstract:
Concrete is an artificial material, which is
made up of cement, fine aggregate, coarse aggregate and
water. In this paper, an attempt has been made to
replace part of cement by Ground Granulated Blast
Furnace Slag (GGBS), Fly Ash (FA), Rice Husk Ash (RHA)
and Silica Fume (SF) to improve the durability
properties of concrete. One of the most requirements of
concrete is that it should be durable under certain
conditions of exposure. Deterioration can occur in
various forms such as alkali- aggregate expansion,
freeze-thaw expansion, salt scaling by de-icing salts,
shrinkage, attack on the reinforcement due to
carbonation, sulphate attack on exposure to ground
water, sea water attack, and corrosion caused by salts.
Addition of admixtures may control these effects. In
this paper, suitable admixtures to improve the
durability characteristics and the optimum percentage of
replacement of cement by mineral admixtures with various
proportions have been studied.
