DURABILITY STUDIES ON THE MULTI COMPONENT BLENDED CONCRETEG.M. GOWTHAMAKUMAR AND R. SUNDARARAJANAbstract Concrete is the most widely used man made construction material in the world and it is second to water as the most utilized substance on the planet. Nowadays the requirements and expectations of concrete in terms of both strength and durability are very high. Four different admixtures are added to modify and improve the properties of the concrete to counteract few adverse environments. The admixtures added in this research work are fly ash, silica fume, calcium nitrate and rice husk ash. By effectively using them, they control pollution which otherwise would not happen. The concrete specimens for M30 grade of the concrete were prepared by replacing the cement with the above said admixture in suitable proportions. Then they were tested for corrosion, chloride attack and sulphate attack in the various durations of 28 days, 56 days, 90 days, 120 days and 180 days. The results proved that the performances of the multi component blended concrete are better than that of the conventional concrete.
