Abstract: The present work is performed for detailed analysis of the sub-systems for the prescribed condition. Its purpose is to provide information to engineers of use of ternary blend of Portland cement in construction of concrete structures. By replacing SUGAECANE BAGASSE ASH with cement was found to boost some properties of the paste, mortar and concrete including compressive strength and water tightness in certain to replace percentages and fineness. Different percentages of SUGARCANE BAGASSE ASH (0%, 5%, 10%, 15%, 20%, 25%, and 30%) and SILICA FUME 10% constantly maintained throughout the mixes for casting of ternary concrete. Concrete specimens are subjected to 7 and 28days curing and later on they are kept in different elevated temperatures. After that specimens are cooled by two different methods such as Air cooling and Water cooling. And then the specimens are allowed for testing. The test results cover the weight loss and development of compressive strength of OPCconcrete and ternary blended mix concrete with different percentages of sugarcanebagasse ash & silica fume and at curing period of 7 and 28 days and its residual compressive strength at elevated temperatures up to 700°C. These target temperatures were 200°C, 300°C, 500°C and 700°C under one hours heating exposure. The test results reveal that ternary blend of Portland cement is attractive for obtaining high strength, low permeability and maintaining workability when compared to ordinary Portland cement.
