Abstract

The study investigated the effects of water to cement (W/C) ratio, curing duration and type of cement on concrete’s chloride concentration under simulated tidal seawater environment. The W/C ratio considered was 0.6 and 0.65, curing duration was 7 and 28 days, and type of cement was type I and type IP. 3% salt solution was prepared for the seawater simulation. The parameters considered had an influence on the chloride concentration especially W/C ratio. The results show that W/C ratio affects the chloride concentration. Increasing the W/C ratio yields a higher chloride concentration. Weaker bonds are produced in high W/C ratio. On the other hand, longer curing duration yields a lower chloride concentration. Curing duration affects the microstructure produced by the cement with the aggregates. As the curing extends, there is more resistance against chloride attack.
