SALVAGE OF CERAMIC WASTE AND MARBLE DUST FOR THE REFINEMENT OF SUSTAINABLE CONCRETE (original) (raw)

Concrete is the most widely used construction material in civil engineering industry throughout the world because of its high structural strength and stability, where the fine aggregate is generally natural sand. The use of sand in construction activities results in the excessive mining, causing depletion of natural resources resulting increase in scour depth and sometimes flood possibility. Ceramic waste is most commonly produced from ceramic industry whereas Marble powder from processing plants during the sawing and polishing of marble blocks. Disposal of both ceramic waste and marble powder is one of the major environmental problems worldwide today. Hence the reuse of waste material has been emphasized to sustainable development. In this research study the (OPC) cement has been replaced by ceramic waste powder accordingly in the proportion of 0%,5%,10%,15%,20%,25%,30% ,35%,40%,45% & 50% and fine aggregate by waste marble powder in the proportion of 0%,5%,10%, 15%,20%,25%,30%,35%, 40%,45% & 50% by weight of M-20 grade concrete. Concrete mixtures were produced, tested and compared in terms of compressive strength of the conventional concrete at 28 days. This paper presents the feasibility of the substitution of ceramic waste powder for cement and marble dust for fine aggregates to achieve economy and environment saving.
