Concrete mix proportion optimization method based on working performance and manufacturing cost

[0038] Embodiment: This embodiment relates to a concrete mix ratio optimization method based on work performance and cost, and the method includes the following steps:

[0039] 1. The quality of each component of concrete is used as the design variable, and the design variables should be as independent as possible from each other. In this example, the concrete is self-compacting concrete, and its components are water, water reducer, stone powder, coarse aggregate, sand, and cement, that is, the design variables are the mass x of water 1 , the mass of water reducing agent x 2 , the quality of stone powder x 3 , mass of coarse aggregate x 4 , the mass of sand x 5 , the mass of cement x 6 . Of course, depending on the concrete components, other components of concrete can also be selected as design variables.

[0040] 2. Determine the objective function with respect to the strength and cost of the concrete. The objective function mainly considers the two factors of concrete...
