Abstract: The construction industry has gained very fast growth in recent decades due to the increase in population, increase in industrialization and also introduction of new infrastructure projects. These resulted in the growth of construction industry drastically, which leads to a huge demand for construction materials and also in generation of huge amount of construction waste. The present work aims at finding the optimum concrete mixture encompassing of cement mortar and brick bat debris as a substitute for fine aggregate. Also the basic properties of cement mortar debris and brick bat debris as fine aggregate was studied and it is compared with the traditional fine aggregate. The effect of cement mortar debris and brickbat debris as fine aggregate in concrete for different proportions on strength was recorded at the curing age of 7, 14 and 28 days. All the data are tabulated andcompared. It was observed that particular proportions of cement mortar debris and brickbat debris displayed enhancing effect onthe compressive strength.
