Abstract

Self-Compacting Concrete (SCC) known as concrete which can flow within its self-weight and without forming honeycombing even with no compaction. In this experimental work, bagasse ash was used as partial replacement of cement with the percentage of 10%, 15% and 20%. The variation of w/c ratio was used e.g 0.275, 0.300 and 0.325. To conduct the durability test, the cylinder specimen with size of 100 x 200 mm to be immersed in magnesium sulfate solution with 5% and 7% molarity for 28 days to observe the percentage of weight loss. The result showed that the value of compressive strength for specimen with w/c = 0.275 and 15% bagasse ash was up to 67.240 MPa for 28 days and 68.096 MPa for 56 days without immersion in magnesium sulfate solution. The highest percentage of weight loss is 3.030% yielded from the specimen with w/c = 0.325 and 0% bagasse ash which was immersed in 7% molarity of magnesium sulfate solution.
