on replacing sand fines in concrete with laterite for structural use. It was discovered that cement/lime stabilized laterite blocks and burnt clay bricks could be used instead of sandcrete blocks since they proved structurally and aesthetically suitable [5]. Attempts have also been made at using coconut shells as aggregate in concrete [6 ÷ 8].

This paper examines the production of calcite and calcite-cement stabilized laterite hollow blocks as low-cost masonry units. First, is the production of laterite hollow blocks solely stabilized with finely ground limestone or calcite followed by the production of laterite hollow blocks stabilized with calcite-cement composite. Laterite was sourced from three locations: Asoro, Evbuotubu and ...
