Conclusion of compressive strength of concrete

2. In concrete tests, although the compressive and flexural strengths of specimens cured at 56 day increase with increasing amount of ash replacement up to 15%, the maximum substitution rate of CBA was determined as 10%. When 10% of CBA is replaced by cement, the com-pressive strength of CBA-concrete increases from 42.65 N/mm 2 to 45.1 N/mm 2
