Laboratory investigation on the strength gaining of brick aggregate concrete using Ordinary Portland cement and Portland Composite Cement

This study focused on the laboratory investigation of strength variation of brick aggregate concrete made with ordinary Portland cement (OPC) and Portland composite cement (PCC).The investigation was conducted by testing concrete cylinder specimens at different ages of concrete with concrete mix ratios: 1: 1.5: 3 and 1: 2: 4 by volume and with water cement ratios=0.45 and 0.60. The test result reveals that at the early age, concrete composed with OPC attained larger compressive strength than the concrete made of PCC. However, in the later age concrete made with PCC achieved higher strength than OPC.
