Experimental investigation on ternary blended cement mortars (original) (raw)

Usage of Ground granulated blast furnace slag(GGBS) and silica fume(SF) in the blended concrete alongside ordinary portland cement(OPC) has been in practice owing to low cost of production, denser microstructure leading to enhanced durability with satisfactory strength properties of concrete. The present study focusses on usage of GGBS and Silica Fume in ternary blended mortars. 1:4 and 1:6 mortars are studied for compressive strength at 3,7, and 28 days of age. Results indicated that compressive strength of mortar cubes was at par with that of control mix upto mixes with 30% GGBS and 10% Silica Fume. Cost analysis indicated a decrease in cost of binder from the mixes with 30% GGBS and 10% Silica Fume in comparison with control mix.
