وصــف النــشرة	The manual approach to design any concrete mixture needs to understand the American Concrete Institute (ACI) Code, including charts, tabular data, and curves. This usually demands interpolations in determining variables that lead to human errors in tracing out and estimating utilized values in the concrete mixture design process. Also, it becomes a tedious task to design the concrete mixture manually. Consequently, a computerized model had been developed using Microsoft Visual Studio for designing the mixtures of normal strength concrete (NC), lightweight concrete (LWC) and high strength concrete (HSC). The computerized model algorithm is created based on converting the ACI code charts and tabular data into mathematical equations. The model outputs included a user-friendly interface for quantifying the concrete mixture's ingredients and the optimal cost estimation. The computerized model accuracy is verified using two methods: first, comparing the concrete mixtures design using the manual design with those obtained from the developed computerized model; and second, comparing the compressive strength used in the computerized model with a field compressive strength obtained from a real concrete mixture that is cast and tested in the field. The results show the high accuracy of the developed model with an error of up to ±0.8%. The cost estimation is optimized with a precision that reaches 0% for the LWC and 0.4% for NC and HSC mixtures.
