Abstract:
Normally, concrete is composed of cement, coarse aggregate and fine aggregate. Analysis of
concrete strength gain was evaluated using the marble powder and steel fiber and post peak
behavior of concrete was studied. Marble powder is obtained as a by-product during the
processing of stone in marble factories. By utilizing this by product as an additive in concrete
we can resolve the problems of land degradation, water sources contamination and pollution
etc.
During the course of study, a concrete of ratio 1:2:4 was prepared with a water cement ratio
of 0.5. Sixty numbers of batches were prepared with 0, 5,10,15,20 % marble by weight of
cement and 0, 0.1, 0.2, 0.3% steel fiber as per weight of cement. Samples were then tested for
slump test and compressive test. Said samples were also checked for their post peak behavior.
Results obtained were three combinations were having highest strength. These combinations
are 0% of marble powder and 0.2% of steel fiber with 4793 psi, 5% of marble powder and
0.1% of steel fiber with 4793 psi and 10% of marble powder and 0% of steel fiber with 4618
psi. Slump test of the same sample was 1.75-2 inches. The results of this study suggest that
up to a maximum of 10% marble powder and up to 0.1% of steel fiber can be used.
