In this paper, Osadebe’s regression polynomial is used to predict the cost of chikoko-cement concrete. The cost model was formulated based on the unit costs of the component materials. The expected cost values were compared with the observed cost values and were found to coincide at all points of observation. The reliability of the model was assessed using F-statistic at a 5% level of significance and was found to be adequate. A computer program written in BASIC language was invoked to select the optimum mix ratios corresponding to the desired overall cost value and vice versa. The computer program is simple and requires less effort to achieve the desired results.
