Due to the fact that traditional concrete mix design methods are characterized with such flaws as process complexity, time consumption, and resource waste, a computer-aided design of concrete mix proportions has become a research hotspot in this field with the development of computer science and optimization algorithms. Therefore, based on the spider curves, a novel concrete mix ratio optimization calculation program has thus been designed using the optimized combination aggregate method. The proposed program is rooted in“the concrete mix design method of the cement slurry volume ratio to aggregate void volume”, integrating relevant literature on concrete mix ration optimization. In the design process, modular programming methods are adopted for an improvement of the readability and maintainability of the program, thus making the program design simpler and more intuitive, so as to achieve the program intelligence and practicality.
