1. A computer-implemented method for redesigning a pre-existing concrete mix design so as to yield a better optimized concrete mix design that guarantees a specific minimum strength at a given slump and at lower cost compared to the pre-existing concrete mix design, the method comprising:

  • identifying a pre-existing concrete mix design that has a design strength, yields concrete having an initial ratio of hydraulic cement, water and air, and has an apparent design K factor based on the design strength and initial ratio of hydraulic cement, water and air;

    inputting into a computing system a revised design K factor that is selected based on the design strength and that more closely corresponds to an optimal K factor corresponding to the design strength compared to the apparent K factor of the pre-existing concrete mix design; and

    the computing system designing a revised concrete mix design having a revised ratio of components using a revised design K factor that is selected based on the design strength, wherein the revised concrete mix design guarantees a specific minimum strength at a given slump and at lower cost compared to the pre-existing concrete mix design.
