2016-11-28  compressive strength decreases. The percentage reduction in compressive strength of 25 % and 50 % replacement level is 11.76 % and 26.95 % respectively. Based on the results, the fall of compressive strength and density of concrete is gradual when the replacement increases. As the percentage of CCTA increases, workability decreases.
