What is CONBUILDMAT D 24 07320 - Reviewer about?
This research paper investigates the effects of phosphogypsum (PG) and washed phosphogypsum (WPG) on the properties of magnesium phosphate cement (MPC) used for coal rock reinforcement. The study finds that WPG significantly enhances the compressive strength and water resistance of MPC compared to PG, with a notable 19.3% increase in strength when using 5 wt.% WPG. Microanalysis indicates that WPG optimizes the pore structure of MPC, resulting in improved mechanical properties without forming new hydration
