Abstract : Strength consideration of concrete with ages has influence sourcing for suitable materials, which can be added to concrete in small quantities without leaving adverse effect on the properties of fresh and hardened concrete. This project examines the possibility of using limestone as an additive, replacing fine aggregate in small quantity in concrete production. The experiment includes sieve analysis which gives a well graded fine aggregate, slump test, compression test, and water absorption rate. The slump result gives a less workable concrete on the addition of limestone in concrete while the water absorption rate of concrete increases on the addition of limestone in concrete mix. The strength attained after 7 and 28 curing days shows that, limestone can be added to concrete in 5% to 10% replacement of sharp sand, in which there is tendency to achieve higher strength with age.
