ABSTRACT
Recent investigations in sustainable construction have been focused on the exploration of agricultural by-products as possible constituent materials in cement-based composites. Cassava peel (peel from cassava tubers) is an agricultural by-product obtained during the production of garri and other cassava-based diets. Cassava peels often constitute nuisance since significant quantities of the peels are discarded as waste. This study investigated the workability and strength behaviour of concrete containing cassava peel ash (cpa). Cpa was used as a pozzolan in concrete at 5%, 10%, 15%, 20% and 25% replacements of portlandlimestone cement by weight. The slump of fresh concrete was determined. The compressive strength and splitting tensile strength values of the specimens obtained at various curing periods, ranging from 7 to 90 days, were compared with those of control concrete specimens. The results showed that the 90-day compressive strength values of concrete containing cpa at up to 15% replacement level are greater than the control strength. Therefore, blended cpacement concrete has the potential of being utilised in concrete construction applications where early strength is a minor requirement.
