Sustainable Concrete Production Through Use of Marble Waste Powder and Silica Fume

Abstract

Sustainability in Concrete Production can be achieved by innovating substitutions for cement and natural aggregates, both coarse and fine. Marble waste is a solid waste material generated during the processing of marble and can be used either as a partial replacement material for cement or fine aggregates while preparing concrete. The marble powder has already been used in previous research works as a partial substitution for fine aggregates. Earlier research indicate that the effects of blending marble waste on the properties of
cement such as consistency, setting times, insoluble residue, and soundness remain within the acceptable ranges of relevant standards. In this research work, feasibility of substitution of marble waste powder for cement has been investigated. Use of marble waste powder in concrete will result in economy in concrete production and environmental benefit. Fresh and hardened properties of different cement composites are investigated. Replacement of up to 22.5% cement with marble waste and 45 % cement with fine aggregates has been tried.
