【 摘 要 】

Steel slag powder was used as a mixed material of magnesium phosphate cement (MPC) to improve its mechanical water resistance. The mechanism of steel slag on MPC was studied through the composition and microstructure test of MPC hydration products. The results showed that the strength of magnesium phosphate cement gradually decreased with the increase of immersion time after adding steel slag. Adding 15% steel slag could improve the water resistance of MPC, make the structure compact and reduce the strength loss rate.
