Effect of Partial Replacement of Sand With Quarry Dust on the Structural Characteristics of Sandcrete Blocks

This work investigated the effect of partial replacement of sand with quarry dust on the compressive strength, flexural strength, split tensile strength and water absorption of sandcrete blocks. River sand was replaced with quarry dust at percentages ranging from 0 to 40 at cement/combined aggregate ratio of 1: 6. The blocks were moulded using a Rosa Commetta block laying machine and were tested after curing by water sprinkling for 28 days. The...
