A STUDY ON STRENGTH CHARACTERISTICS OF TERNARY BLENDED CONCRETE WITH VARYING PERCENTAGES OF COARSE AGGREGATE WITH SINTERED FLY ASH AGGREGATE

In the present research work,OPC has been replaced with different percentage of pozzolanic materials viz. FA, GGBS, SF to arrive at targeted strength of concrete (M55). The lightweight aggregate i.e., SFA aggregate has been proposed to replace the conventional mineralogical coarse aggregate (CA) and study the strength characteristics of concrete. An array of results, characteristics data obtained after the laboratory experiments on concrete cubes, compiled, analyzed and inferences drawn. The results are critically examined vis-à-vis intended strength characteristics and its variations for different percentage of replacement of cement and coarse aggregate content. The analyses of the experimental results indicate that the strength characteristics are reducing with increasing % of replacement of CA with LWSFA in all combination of TBC. However, the rate of reduction is more in C+FA+GGBS combination and least in C+FA+SF combination.
