Abstract: The engineering and construction industry has faced many challenge for consuming, “Sustainable green and recycled products” in manufacture of concrete. Coal Bottom Ash (CBA) has the potential to be used as concrete materials in place of fine aggregate. Bottom ash is the dominant solid residue generated in power stations. In this study, experimental investigation has been conducted to assess the performance of bottom ash as fine aggregate with various percentages (20 %, 40 %, 60 % & 100 %) in cement concrete subjected to chemical curing. The concrete specimens were casted and tested for compressive strength and tensile strength at 7, 28 and 90 days. The functional properties like Sorptivity, Water Permeability, Rapid Chloride Penetration, Sulphate and Acid Resistance were tested on 28, 56 and 90 days old specimens. It is observed that bottom ash replacement up to 40 % as fine aggregate in cement concrete is durable.
