Abstract
The earth's surface is covered with approximately thirty percent landmass and seventy percent water, ninety-seven percent of which is seawater. Infrastructures like piers, ports and bridges which are made of concrete are inevitably exposed to seawater which is very corrosive. Corrosion of reinforcing steel inside the infrastructure is one of the primary reasons of structure failure. Sugarcane Bagasse Ash (SCBA), which is a known pozzolanic material, has been found to improve the durability of concrete by decreasing its porosity. In this study, the effect varying curing period on the durability of concrete submerged in actual marine environment containing SCBA as cement replacement was investigated. A total of 24 specimens were casted (0, 10% SCBA cement replacement) and subjected to four different curing periods 7, 28, and 90 days. After curing, the samples were exposed to actual marine environment for 60 days. After submersion, the samples were subjected to colorimetric test for chloride penetrations measurement. Experimental results show that there is no significant difference in the chloride penetration depths between specimens with 0% and 10% SCBA especially at longer curing period.
