Abstract: Service life prediction, this project can play out its primary function inside the required life expectancy while guaranteeing worthy support cost. In this paper, the service life of structures presented to aggressive conditions is estimated by the plausibility of splitting and spalling of concrete cover by conducting the investigation on 120 specimens (150 mm x 150 mm x 150 mm). And vary the water-cement ratios of 0.3, 0.4, and 0.5 with respective percentage of ground granulated blast furnace slag(GGBS) added in mix of W/C- 0.3 (90%, 80%, and 70%), W/C-0.4 (80%, 70%, and 60%) and W/C- 0.5 (70%, 60%, and 50%) each ratio contains 40 cubes (18 and 12-with material compressive strength and NaCl exposer, 4 and 6 without material compressive strength and NaCl exposer) compared with respective of their curing days 28 and 90. NaCl specimens are used to drill depth (5-10 mm, 10-15 mm and 15-20mm,20-25mm) and take the powder and predict the penetration depth of chemical through the specimen and compared with and without NaCl exposer specimens. The Penetration depth of chloride ion into specimen is restricted by w/c-0.3% of 90% GGBS is give better results than others.
