Abstract: Service-life prediction of reinforced concrete has been extensively studied in the past two decades. It is seen that RC structures have expected to have life more than 100 plus years with effortless maintenance in spite of reinforced concrete structures getting exposed to harsh environments To achieve this objective, durability of structures are required to be produced. To do this, a durable structure needs to be produced. In this work ground granulated blast furnace slag(GGBS) is added to concrete at different levels of replacement. GGBS is replaced in cement at the rate of 50 %, 60 % and 70 % and its strength and chloride penetration of concrete is determined. Chloride ingress is a critical attack of environment on concrete structure, which corrodes the steel reinforcement and thereby reduce the strength, serviceability and aesthetics of the structure. This is the basic reason for frequent repair and early replacement of structure. To prevent deterioration due to chorine penetration is using concrete which are resistant to chloride attack. This is possible by understanding the ability of chlorine ion penetration in the concrete at the design, production and quality control cycle. Chloride ion penetration is a slow process and cannot be determined in specific time frame to set standards of quality before it is put to use. To predict the service life and to asses chlorine penetration, accelerated test procedure and predictive model is required to determine the value of chlorine diffusion in specified period of time.
