Ferrous and non ferrous metal casting industries produce several millions tons of byproduct in the world. In India, approximately 2 million tons of waste foundry sand is produced yearly. WFS is major byproduct of metal casting industry and successfully used as a land filling material for many years. But use of waste foundry sand (WFS) for land filling is becoming a problem due to rapid increase in disposal cost. In an effort to use the WFS in large volume, research has being carried out for its possible large scale utilization in making concrete as partial replacement of fine aggregate.This experimental investigation was performed to evaluate the strength and durability properties of concrete mixtures, in which natural sand was partial replaced with (WFS). Natural sand was replaced with five percentage (0%, 5%, 10%, 15%, and 20%) of WFS by weight. A total of five concrete mix proportions (M-1, M-2, M-3, M-4 and M-5) with and without WFS were developed. Compression test and splitting tensile strength test were carried out to evaluate the strength properties of concrete at the age of 7, 28 and 91 days. Modulus of elasticity and ultrasonic pulse velocity test were conducted at the age of 28 and 91 days. In case of durability property, Rapid Chloride Permeability test was performed on all five mix proportion at the age of 28 and 91 days. Test result indicate a marginal increase in strength and durability properties of plain concrete by inclusion of WFS as a partial replacement of fine aggregate.
► This paper is utilization of waste foundry sand (WFS) as partial replacement of fine aggregate. ► Fine Aggregates (Sand) has been replaced with 0%, 5%, 10%, 15%, and 20% WFS. ► Strength properties such as compressive strength, splitting tensile strength, and modulus of elasticity were investigated. ► Ultrasonic Pulse Velocity and permeability (chloride) were also studied. ► In this investigation, WFS studied results in denser and durable concrete.
