Abstract

This study investigated the resistance of RHA blended Type I concrete against chloride penetration. Varying only the percentage of RHA mixed to determine the optimum mix, samples with 0%, 5%, 10% and 15% RHA were prepared using the JSCE method. The specimens were cured for 28 days and were exposed to seawater afterwards for 30 days. To measure the chloride penetration depths, the specimens were cut transversely into halves by using a Universal Testing Machine Colorimetric method was applied using AgNO3 solution. The depths were easily measured using a Vernier caliper. The data gathered were analyzed by the use of Statistical Package of the Social Sciences (SSPS) software. One way analysis if variance (ANOVA) was applied and the results were further analyzed by a multiple comparisons test called Tukey's method. The results have shown that 10% RHA is the best among the four mixes because of minimized cement usage and almost the same chloride penetration resistance as OPC.
