Study of Optimum Replacement Percentages of Marble Waste Aggregate and Stone Dust in Concrete

Abstract

From the marble processing units approximately 70% of the raw material converted into solid and sludge waste. Similarly, from quarries and stone crusher plants after segregating the coarse aggregates, finer particles of stone dust also discarded as an unwanted material which either piled up outside those plants or drained into water channels. These solid and semi-fluid waste material from marble industries and crushing plants remains a source of air, water and land pollution. In the production of normal strength concrete, the disposal of same materials i.e. marble waste aggregate (MWA) and stone dust (SD) as partial replacements of coarse and fine aggregates respectively was substantiated in this study.
