Utilization of Waste Foundry Sand As Partly Substitution of Fine Aggregates For Establishing Sustainable Concrete

Abstract

Natural sand is in high demand as a fine aggregate in concrete for construction projects. In India, metal casting sectors created waste foundry sand (WFS) in million tons. WFS disposal and environmental concerns were kept to a minimum. WFS can be utilized in concrete as a partly substitution of fine aggregate. The usage of WFS in concrete makes it economical. This research discusses the influence of combining WFS with fine aggregate in concrete. In M40 grade concrete, fine aggregate is partly substituted with WFS in the interval of 0%, 15%, 30%, and 45% by weight. The results of experimental research to check the compressive strength and split tensile strength of WFS at all substitution levels for curing periods of 7, 14, and 28 days. Experimental test findings indicated a minor improvement in the compressive and split tensile strength upto 30% substitution of WFS, after which strength decreased as referred to the control mix M-0.
