PERFORMANCE OF CONCRETE BY USING HYPO SLUDGE AS A MINERAL ADMIXTURE

Abstract

Increase in the paper waste from paper industries become most serious disposal problem by occupying large space and environmental pollution which is raising every day. To reduce the paper waste and environmental pollution, it is proposed to use the paper waste as Hypo sludge in concrete mix which contains cementitious properties like silica and magnesium. The main ingredient of concrete is cement. During the manufacturing of cement, large amount of carbon dioxide is released into the environment which causes global warming. To control environmental pollution from cement industries, Hypo sludge is used as a partial replacement of cement so that it can reduce cement content and support as an eco-friendly building material. In this research cement is replaced with fly ash and Hypo sludge. By adding 0 percent,3 percent,6 percent,9 percent 12percent and 15percent of hypo sludge, compressive and split tensile strength of concrete and also performance of Hypo sludge concrete are studied. From the experiment, compressive strength and split tensile strength of Hypo sludge concrete increases up to optimum dosage.
