Abstract
Building collapse is a common phenomenon all over the world. However, its dire consequences of loss of live and properties makes such incidences a worrisome situation. Choice of aggregate sizes, concrete mix ratio and cement types are some of the factors associated with cases of this menace. Consequently, this study considers these factors with a view to providing an optimized concrete-mix-design for different types of cement brands available in Yewa South Local Government area of Ogun State. Sieve analysis was carried out on the various sizes of granite (9.5mm, 12.5mm, 19mm and 25mm), appropriate combination ratio of the various granite sizes were determined and used in casting concrete cubes which were subjected to compressive strength tests. Optimal concrete strength for each aggregate size and combination of sizes were determined at 7days, 14days, 21days and 28days for each cement brand. Results reveals that the combination of granite of various sizes of 19mm, 12.5mm and 9.5mm in the ratio 1:0.5:0.32 for Dangote cement of grade 42.5N has the highest compressive strength of 36.64N/mm2. While that of Larfage is 26.60N/mm2 and that Purechem cement is 25.29N/mm2.
