Abstract: During the last two decades, concrete had encountered with the problem associated to its destruction through the attack by external agents like chlorides, carbon dioxide and other deleterious substances. In order to solve this problem, extensive research had been carried out in the field of SCM's as a part replacement of cement whose purpose is to serve as a durability enhancer for concrete to ensure longer service life. In our research study thrust has been laid to discover a suitable accelerated testing technique which would serve as a tool for service life prediction for RCC consisting of SCM's exposed to chloride environment. Present study deals with three varieties of cement, one non-blended cement (OPC) and other two cements blended with slag and fly ash. Generalized curves are drawn in order to rationalize the behavior of different varieties of cements against the various accelerated test methods for six w/c ratios. The results of accelerated tests are compared with conventional chloride diffusion test done by immersion method. The purpose of formulating these generalized curves is to develop a performance based service life design guidelines and quality control measures for evaluating concrete durability in the field made with these binders.
