1. A method of determining whether an existing concrete composition having a given design strength and given ratio of components is overdesigned without having to (i) prepare a concrete test sample, (ii) allow it to harden, (iii) test its actual strength, and (iv) compare the actual strength of the test sample with the given design strength, the method comprising:

  • determining an apparent design K factor for the existing concrete composition based on the given design strength of the concrete composition and the given ratio of components within the concrete composition; and

    comparing the apparent design K factor with a more optimal K factor that corresponds to the given design strength and which is selected from among a plurality of different K factors that vary with varying concrete strength.
