Abstract

Concrete cubes produced from Bama gravel (Category B) using varied mix proportions and water-cement ratios were subjected to compressive strength and density tests at the curing ages 7, 14 and 28 days. The results indicated that the strength of 28.00Nmm-2 was recorded from the mix proportion of 1:1/2:4 and water-cement ratio of 0.55, which corresponds to a density of 2495 kgm-3. A careful inspection of the results obtained generally shows that the strenfths are inversely proportional to the fine aggregate content and water-cement ratios. It is recommended that great care should be taken while mixing the aggregate proportions of the Bama gravel in order to obtain high quality medium grade concrete for construction purposes.
