摘要：

Laterite is a dominant soil material in Nigeria but its use in structural concrete has not been overly explored. In this study, ceramic wastes obtained from construction and demolition activities and laterite were used as replacement for natural aggregates. Workability and strength characteristics of the concrete and microstructure of selected samples were obtained. Results showed that natural aggregate concrete was more workable than the laterised concrete. Both the compressive strength and splitting tensile strength increased with curing age, however, laterised concrete with 10% laterite content and 75% ceramic coarse aggregate yielded higher strength at 28 days than the reference concrete.
