Experimental Investigation on Low Grade Cement by Using Waste Products

Abstract

Demand and consumption of cement is increasing day by day which has led researchers and scientists to search for locally available alternate binders that can replace cement partially and are ecofriendly and contribute towards waste management. In this research cementious materials such as hydrated lime, fly ash, sugarcane bagasse ash, sewage sludge ash, and ceramic waste are used as replacement to reduce costs and environmental pollution associated with the production of cement. OPC 53 grade cement is used in the study. In this research study the (OPC) cement has been replaced by hydrated lime, fly ash, sugarcane bagasse ash, sewage sludge ash, and ceramic waste accordingly in the range of 0%, 45%, 50%, 55% & 60% by weight. The effect of replacement of cement by above waste products is tested and compared in terms of compressive strength to the conventional mortar. Mortar was proportioned in 1:5 cement sand ratio. The compressive strength test was conducted on the masonry mortar cubes.The compressive strength of mortars was measured at 7 and 28 days. As a result, the compressive strength achieved up to 50% replacing cement with above waste products.
