Experimental Study on Strength of Water Hyacinth Ash as Partial Replacement of Cement in Concrete

Abstract

Concrete is an artificial material which composed of cement, fine aggregates, coarse aggregates and water. The main constituent of traditional and ordinary concrete is cement. Cement production emits a huge amount of carbon dioxide in the atmosphere. To reduce carbon dioxide, cement is replaced as a supplementary cementitious material in concrete. Water hyacinth grows vigorously in ponds and doubles the quantity within two weeks. The studies have been done to evaluate water hyacinth ash in the replacement of cement. The Present study reveals about the different proportion of water hyacinth ash replacing cement, which will affect the properties of workability, compression, and split tensile strength of concrete. Concrete is cast in cubes and cylinders with different percentage (0, 10%, 20% by weight of cement), The casted specimens are removed from the mould, cured and tested for 7, 14 and 28 days. The tested result were compared with conventional concrete and the different ratio of WHA replaces cement concrete in comparing the concrete and WHA replacement concrete, the ultimate strength achieved at 10% for M30 grade. .
