The mathematical model of the strength of phosphogypsum polymer was obtained by experiment and numerical simulation method. The physical and chemical properties of phosphogypsum and cementitious material were analyzed by optimization ratio experiment, and the optimal ratio was obtained. The compressive strength of the composites was simulated and the ternary phase diagrams of Kα and SiO2-Al2O3 were obtained. The mathematic factor analysis method was used to establish the mathematical model of the strength of geopolymer. The additive, gray Sand ratio and water-cement ratio on the strength of the geopolymer. Through the qualitative analysis of the hydration mechanism of the geopolymer, the linear relationship between the strength and the volume and density of each component was deduced. Combining the two geopolymer System to verify the comparative analysis, so as to construct a mathematical model of the intensity of phosphogypsum base polymer, and lay a theoretical foundation for experimental research and industrial application.
