Influence of slag blended cement concrete on chloride diffusion rate
This research was conducted to investigate the effect of 0 % to 30 % partial replacement of cement by slag on chloride diffusion rate in concrete. Concretes with 0 % to 30 % slag were used and exposed to 2 % to 5 % NaCl solutions. The effect of different external salt concentration solutions and the influence of water-cement ratios ranging from 0.45 to 0.75 was also studied. In this research, different curing methods such as 9 days to 18 days exposure to 100 % humidity and 9 days to 18 days submersion in distilled water were selected. The results indicated that after 90 days of exposure to salt solutions and 108 days of concrete age, chloride diffusivity for concretes containing slag almost remained the same. This effect was more pronounced for water-cement ratio of 0.45 and curing condition of 18 days submersion in water. An increase in water-cement ratio beyond 0.55 indicated a higher chloride diffusion rate. Curing condition for slag blended cement concrete also indicated a different behavior in chloride diffusivity. The best curing method obtained for this type of concrete was 18 days submersion in water.
