Foundry sand waste materials (samples) were collected from ten different industries and studied for the application in the construction of road and as a structural fill. Physical, chemical and geotechnical characterization were carried out in the laboratory. Out of 10 samples, 2 samples (coarser and finer) were stabilized with cement in the range of 2–8% and cured for different periods (7–28 days). Unconfined compressive strength (UCS) and indirect tensile strength (ITS) of both stabilized samples were determined. Different parameters were derived viz. stiffness modulus, cohesion and ratio of UCS/ITS of stabilized samples. The effect of curing period and cement content were analyzed on these parameters. UCS, ITS, cohesion and stiffness value increase with cement content and curing period similar to conventional material. It was inferred that finer sample may be used for the construction of subbase layer of pavement while both samples may be used as a structural fill which will lead to sustainable construction.
