Abstract

Result of grading test conducted on some samples of granite collected from some quarry sites in Ogun State was found to fall short of the requirements of BS 882:1990. Based on reviewed literature, the various sizes were combined in an obtained ratio so as to meet the requirements. Compressive strength test was then carried out on concrete cubes containing granites mixed in the combination ratio obtained from the study. The combination 19mm, 12.5mm and 9.5mm in the ratio of gives the highest compressive strength of 36.64N/mm2. This is therefore adjudged to be the optimal mix proportion of granites for producing concrete for building construction.
