Physical and Chemical Properties Research for Phosophogysum-Based Silicon and Aluminum Composite Materials

Abstract:

In this paper, the phosphogypsum-based salic composite binder is the main study object, the particle size distribution, chemical composition and mineral composition of the components have been tested and analysed; According to the ratio experiments, a rational proportion range of the phosphogypsum-based Si-Al composite binder has been summarized; meanwhile, experiments have been designed for composite binder’s activity characterization by using the method of activity rate K_ª , and the extent which the K_ª value is affected by the external environment is Temperature > Curing time > Fineness; then scattered points on the dissolved quantity of active Al₂O₃、SiO₂ and the compressive strength at 90d is simulated by Matlab, and simulation results show that the compressive strength at 90d linearly increased with the increasing of dissolved quantity of active Al₂O₃、SiO₂.
