Abstract

The purpose of this research work is to compare the effect of coarse aggregate sizes on the strength of concrete. Materials for this study were (water, fine and coarse aggregates and cement). Acceptability criteria for tests on basic materials for concreting were ascertain such as; water according to BS 2690 standard, Fine and coarse aggregates according to BS 812:1975, part 1 to 4 standard and Cement according to BS 12:1991. The acceptability criteria for testing fresh and hardened concrete such as Workability test (slump test in accordance with BS 1881:1983, part 102) and Compressive strength test (cube test in accordance with BS 1881:1983. The specimen size for crushing strength was 150mm x 150mm x 150mm, cured and tested for 7, 14 and 28 days with concrete grade 20 of minimum compressive strength of 14 N/mm2 (mix ratio of 1:2:4). From the result gotten, the concrete strength of aggregate size of 20mm to 28mm after 28 days was higher than that of 13.2mm to 19mm and that of 3.35mm to 10 mm.
