Abstract : Cement production imposes major environmental and economic burdens in Nigeria. This study evaluated locally sourced cassava peel ash and waste paper ash as partial replacements for ordinary portland cement in concrete of nominal M25 grade. The ashes were produced by controlled incineration and sieved to 75µm, and their chemical oxide composition was determined.

Keywords : Cassava Peel Ash; Waste Paper Ash; Ordinary Portland Cement; Supplementary Cementitious Material; Compressive Strength; Pozzolan; Sustainable Concrete.
