Concrete is a universal material of construction due to its versatility. It is made up of a combination of different constituent materials which are water cement, fine and coarse aggregates. These materials have diverse properties which are brought to bear on the overall properties of the product (concrete). The variation in the content of these various constituents will affect the different properties of concrete especially the compressive strength. This study is therefore geared towards evaluating the influence of such variations on the compressive strength of concrete. 27 trial mixes were produced and the 28 days compressive strength was determined. The results subsequently obtained from the trial mixes were analyzed to formulate a regression model for concrete mix proportion. The result of the predicted compressive strength was examined to evaluate the effect of the variation of the various constituent materials. The result shows that variation by weight of each of the constituent materials results in variation in the compressive strength of concrete
