ABSTRACT: This study compared the varying percentages of modified Type IP cement concrete with cogon (imperata cylindrica) ash in terms of chloride penetration depth. The cogon ash partial replacement to Type IP cement varied from different percentages, specifically 2%, 4% , and 6%. Concrete specimens underwent 28-day during period and submerged in 3% NaCI solutions for an additional 28 days to simulate seawater conditions. The chloride penetration depths were measured and analyzed using the AgNO3-based colometric test. Using Linear Regression Product-Moment Correlation Coefficient, and One-way analysis of variance (ANOVA), the findings indicated that partially replacing cement with cogon ash in the 28-day cured concrete mixture lowered the chloride penetration depth. Among the partial replacement percentages, the controlled sample has the highest chloride penetration depth while the concrete specimens with 4% cogon ash replacement displayed the lowest chloride penetration depth. The differences among these replacement percentage are statistically significant. Thus, this study recommends the use of cogon ash to improve the chloride penetration resistance of a concrete. |
