Abstracts: In the present study, effect of foundry sand is added in fine aggregate with the compressive strength having mix proportions of 1:1.58:3.26:0.50 was investigated. Fine aggregates were added with three percentages of foundry sand. The percentages of addition were 10, 20 and 30 % by weight of fine aggregate. Tests were performed for compressive strength, for all addition levels of foundry sand curing periods of 28-days & 7-days. Test results showed that there is some increase in compressive strength, after adding the fine aggregates with certain percentage of foundry sand so foundry sand can be safely used in concrete for durability and strength purposes.
