Abstract
This experimental study is intended to investigate the applicability of existing relationships as prescribed in IS: 9013-1978 between the accelerated curing compressive strength and actual compressive strength of ternary-blended concrete. Class F type Fly ash (FA) was used to develop binary-blended concrete by replacing 20% of cement in the mixture and Rice Husk Ash (RHA) was also used to prepare another binary-blended concrete by replacing 18% of cement. Further Silica Fume (SF) was used for preparing ternary-blended concrete at 4, 8 and 12% by replacing the weight of cementitious content. Analysis of the test results shows that the relationship between accelerated curing compressive strength and the actual compressive strength is interrelated and the constant in the correlated equations specified in the code were found to be inaccurate in all the blended combinations. Thus, the alternative relations were proposed for the ternary-blended system with the supports of results and figures.
