In this study micro-silica was used in concrete paving block as a partial substitute of cement. Fresh, mechanical and durability properties of concrete paving blocks is investigated int this study. For this study, microsilica was replaced with cement, at replacement rates of 2.5% ,5% ,7.5% and 10% (by weight). The result shows that the workability of concrete is decreased with increase in replacement percentage of cement with micro-silica. The compressive strength test at 28 days showed the

The results of mechanical property tests showed that the specimen with 5% micro-silica showed comparable performance to that of the control concrete sample. Test results of water absorption and water penetration of all the mixes is less than that of control concrete paving blocks.
