Abstract
Concrete is a composite material which has wider application in construction industry because of strength and durability. The four components used in producing cement concrete generally are cement, water, sand and aggregate. But, natural sand is being depleted at present and also becoming costly, particularly in the rapidly developing countries like India. Hence, there is a necessity to develop a substitute for the fine sand for use in the concrete mixture, one of which is the manufactured sand developed from locally available quarry dust. Therefore, in this study, investigations are carried out to determine the mechanical properties of quarry dust and Slurry Infiltrated Fibrous concrete (SIFCON) made with the quarry dust. SIFCON possesses the high strength as well as large ductility because of its high tensile strength.SIFCON fibre content ranges from 4 -20% by volume. The specimen has partial replacement of fine aggregates by quarry dust as 15%, 30% and 45%
