Abstract
The study focus on assessment of normal concrete made with gravel obtained from Ogun and Oyo States, Nigeria. In this vein, gravel types from four commonly used mining pits namely: Iyana Abib, Sabo, Alamutu and Igbo-Ora were considered. The method of study was purely experimental. The conventional mix ratios used were 1:2:4 and 1:3:6. The grading of fine and coarse aggregates were determined using sieve analysis, while the tests performed on fresh concrete were slump and compaction factor. Compressive strength test was executed on the hardened concrete. Concretes were made using 150 mm concrete cubes. The concrete was tested on the 3, 7, 14, 21 and 28 days. The average compressive strength obtained for 1:2:4 mix ratio were 25.3 N/mm2 (gravel from Igbo-Ora), 23.7 N/mm2 (gravel from Alamutu), 19.7 N/mm2 (gravel from Sabo) and 13.5 N/mm2 (gravel from Iyana-Abib). Also, the average compressive strength on the 28 days obtained for 1:3:6 mix ratio were 20.5 N/mm2 (gravel from Igbo-Ora), 19.5 N/mm2 (gravel from Alamutu), 15.4 N/mm2 (gravel from Sabo) and 9.9 N/mm2 (gravel from Iyana-Abib). Minimum requirement of 20 N/mm2 by BS 8110:1997 and ACI 318:2008 for 1:2:4 mix ratio was satisfied by gravel from Igbo-Ora and Alamutu. Also gravel from Igbo-Ora, Alamutu and Sabo satisfied 15 N/mm2 minimum requirement by BS 8110:1997 and ACI 318:2008 for 1:3:6 mix ratio. It was concluded that gravel from Igbo-Ora produced the highest strength for both 1:2:4 and 1:3:6 mix ratio and is recommended for construction work where granite is not available or uneconomical.
