The results obtained from compressive strength test for all the mixes are given in fig 1. It can be seen from the
figure that the compressive strength results of specimens at 10% replacement of SCBA were higher than those at 0% SCBA.
Further increase in SCBA percentage results in decreasing compressive strength along with significant fall in properties of
fresh concrete. It is also indicated that the rate of increase of strength of mixes with SCBA is higher at later days that may
be due to pozzolanic properties of SCBA.
