This research work investigates and evaluates the effects of varying lime composition on the compressive and flexural strength of compressed silicate limestone bricks and compares the results to the local blocks and bricks used in the Kenya market. The mix ratio used to make limestone bricks was binder (cement replaced with hydrated lime powder), sand and water cement in ratio of 1:5:0.4. The results showed that an increase in the lime content results into a decrease in the strength properties of the bricks. Clay brick, natural stone block and concrete blocks were bought in the local market and crushed for comparison. It was observed that the optimum strength performance was obtained at 60% cement replacement with lime which corresponds to 6.08 and 3.05 MPa, respectively for compressive and flexural strength.

Key words: Clay brick, natural stone block, silicate limestone compressed bricks, compressive strength and flexural strength.
