Abstract: The main objective of the study of this work is to re-use the used foundry sand (produced at foundry industries) as a partial replacement to fine aggregate in different percentages (15 to 50%) that can be adopted in concrete along with normal river sand designed to meet the requirements of concrete of grade M50, using foundry sand with OPC have been considered in the study. Though, the main investigation is to be carried out is on the flexural behavior of reinforced foundry sand concrete beams, to facilitate proportioning of foundry sand concrete, compressive strength studies are also carried out. The tests to be carried out on around (18) singly reinforced beams of size 150 mm x 250 mm & overall length 2000 mm, simply supported over effective span 1800 mm under pure bending. The beams will be provided with adequate shear reinforcement so that the failure of the beams may due to pure flexure. The grade of concrete M50 generally with three foundry sand replacement levels (FSL) in each grade i,e, 15%, 25%, & 35% FSL are considered.
