Influence of calcined laterite on the physico-mechanical, durability and microstructure characteristics of portland cement mortar
Innovative Infrastructure Solutions(2024)
Abstract
Most investigations in the literature concerning cement replacement with supplementary cementitious materials (SCMs) have predominantly focused on the utilization of fly ash and slag, which are not universally available. Laterite soil presents itself as a potential alternative to these commonly used SCMs, particularly where availability is an issue. Commonly found in tropical and subtropical regions, laterite soils have been extensively employed in building construction. Therefore, the present study aims to explore the incorporation of laterite soil calcined at 600 °C as a substitute for Portland cement (PC) in mortars, with the objective of producing sustainable construction materials. The effect of calcined laterite (CL) passing 75 μm sieves as 10, 30 and 50
