Cementing material mix proportion design method based on close packing theory

The invention relates to the technical field of building material preparation, in particular to a close packing theory-based cementing material mix proportion design method. The method comprises the following steps: taking cement as a matrix, determining mineral admixture components of the matrix, and measuring particle size distribution of different mineral admixtures through a laser particle analyzer; establishing a close packing model of the mixed material according to a Dinger-Funk equation obtained by an improved Andersen model and an improved Andersen model, determining the volume ratio of each component in the mixed material during close packing, determining a distribution coefficient q reaching a relatively close packing state through the maximum wet packing density, and determining the mix proportion of each component by utilizing least square fitting; gEMS software is used for simulating the maximum mixing amount of the mineral admixture, the mixing proportion of the cementing material is adjusted t
