| Abstract | A program has been developed for concrete mix design methods prescribed by American Concrete Institute (ACI method) and Department of the Environment (DOE method). Both methods are empirical and based on experimental data and experience. It takes time and effort to carry out the mix design manually. This program serves as a tool for the faster and easy determination of the mix proportions of concrete satisfying a particular set of specifications. The designer can make a quick decision about the adoptation of any method by comparing the computed results with the trial batch observations. The results obtained from numerical examples indicated that the water-cement ratios prescribed by the ACI method are lower than those by the DOE method for the same compressive strengths. Moreover, the aggregate-cement ratios are also lower using the ACI method which again reveal that a mix designed by the ACI method is richer and more expensive as compared to one designed by the DOE method. Finally, the DOE method, being more economical is recommended to be tried first. Unless the results of the trial mix are satisfactory, the ACI method should be used as an alternative. |
