<p>With increase in quantities of industrial bi-products, solid waste management is of special significance. Approximately two million tons of Waste Foundry Sand (WFS) is produced yearly in India. Improper disposal of waste foundry sand impose environmental effects such as inhibition of soil microbial activity and ground water toxication. Using WFS as a building materials can effectively reduce the environmental effects and disposal concerns. Strength requirements and cost reduction is achieved by partially replacing cement with fly ash. Polypropylene fibre increases the ductility of the concrete. In this paper, work behaviour of M25 concrete was studied by replacing natural sand with WFS (10%, 20% and 30%) by weight, cement with fly ash(20%, 25% and 30%) by weight and polypropylene fibre was added (0.5%, 1% and 1.5%) by weight of cement. The mix proportion parameters of the concrete were analysed using Taguchi method for optimal design of experiments. Concrete mixtures were designed in L9 orthogonal array with three control factors namely WFS, fly ash and polypropylene fibre. The mixtures were tested both in fresh and harden state, and the optimized mixture was identified based on the test results using Signal to Noise ratio. © 2018 Elsevier Ltd.</p>
