Abstract: This article reports on a research carried out to assess the effects of manufactured sand in concrete, produced with palm kernel shells as coarse aggregate; on the strength, weight in air and workability. The concrete was designed using British Building Research (BRE) method, and a total of 54 cubes were made of 150mm by 150mm by 150mm.
