【 摘 要 】

It is a well-known fact that India is one of the countries with agriculture as its primary profession. In the recent past, many agro-based industries have been developed and they continue to grow. Sugarcane industry is one among them. With an increase in the number of industries, pollution of all sorts has also increased enormously. Sugarcane, which is heated after being used in the manufacture of sugar, leads to the formation of ash as an industrial waste known as Sugar Cane Bagasse Ash (SCBA). Since SCBA possesses pozzolanic properties, it can be used as a partial replacement for cement in concrete, in order to reduce the emission of Carbon dioxide (CO2) into the atmosphere caused during the production of cement. In this current research, a Ternary Blended Concrete (TBC) comprising SCBA and Silica Fume (SF) as the replacement materials for cement has been taken up for study, subjecting it to the following two conditions: i) elevated temperature and ii) curing under sea water. The above parameters have been chosen so as to investigate the behavior of TBC with respect to its resistance to very high temperatures in the incidence of fire accidents and its suitability for construction in coastal areas. Specimens of concrete mixes were subjected to elevated temperatures followed by different cooling regimes; various tests were conducted on those specimens such as compressive test, shrinkage test and sorptivity test. TBC was found to exhibit better results in all such conditions.
