Abstract: This study is aimed at investigating the compressive strength of concrete using locust beans waste ash (LBWA) as a replacement for cement in concrete using three grades of concrete; grade 20, 25 and 30 respectively, the concrete cube cast was; control (0%) 5%, 10% and 15% respectively. the cube was cast, cured and tested at 7days, 14days. 21days and 28days. Although the results of this study have shown a significant reduction in compressive strength of concrete utilizing LBWA than normal concrete, it could be recommended that LBWA concrete should be used in road curbs, concrete blocks, non-bearing concrete walls, precast units (partition walls, concrete blocks for Architectural applications and some cases of slabs on soil, culverts, sidewalks, driveways, foundation pads for machinery.
