Abstract
This study investigated the effect of ceramic waste powder (CWP) as a partial replacement of cement on the mechanical performance and durability of concrete, with the aim of promoting sustainable and environmentally friendly construction practices. The experimental work was carried out between August and September 2025 at the Civil Engineering Laboratory, University of Benin. Ceramic waste was crushed and ground to pass a 75 µm sieve, and concrete mixes with 0%, 5%, 10%, 15%, and 20% CWP were produced at a 1:2:4 mix ratio and a constant water–cement ratio of 0.55. Compressive strength was tested at 7, 14, and 28 days, while durability was assessed using water absorption and sorptivity.
