Foundry sand, a byproduct from casting of ferrous and non-ferrous metals, poses significant challenges for waste disposal, with an estimated 6-10 million tons discarded worldwide annually. This study explores the effects of replacing natural sand with waste foundry sand in a mortar mix of 1:3 on the compressive strength of cement blocks sized 7.07 x 7.07 x 7.07 cm³. Various proportions of waste foundry sand replacement (0%, 10%, 20%, 30%, 40%, 50%, and 60%) were tested on blocks aged 3, 7, and 28 days. It was observed that an increase in waste foundry sand replacement resulted in a decrease in the weight of the blocks. Correspondingly, the compressive strength reduced from 19.18 N/mm² at 0% replacement to 11.71 N/mm² at 60% replacement on the third day and decreased from 39.02 N/mm² to 16.97 N/mm² on the 28th day. These findings highlight the negative impact of waste foundry sand on compressive strength, emphasizing the need for efficient waste management strategies in cement production.
