Abstract
In this paper, Scheffe’s simplex lattice design technique is used to optimize the overall cost of chikoko-cement concrete. The cost model was developed based on the unit costs of the chikokocement concrete ingredients. The predicted cost values were compared with the observed cost values and were found to be in consonance at all points of observation. The reliability of the model was investigated 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 a given cost value and vice versa. The computer program requires less effort to execute.
