Abstract

The influence of the constituent materials of concrete on its overall properties and performance cannot be over emphasised. This study analysed effect of using different brands of cement on optimized aggregate gradation for different sizes of coarse aggregate using ANOVA. The calculated F values for 12.5mm single size and 12.5mm combined aggregates are 9.35 and 143.3 for the different aggregate forms and the different brands/grades of cement respectively. Similarly, that of 19mm single size and 19mm combined aggregates are 40.36 and 603.36 while that of 25mm single size and 25mm combined aggregates are 27.11 and 301.72 respectively. These results imply that there are significant differences in the sample means for both the different aggregate sizes from the various cement brands/grades
