摘要：
The effect of waterglass on the anti-washout ability of potassium and magnesium phosphate cement(MKPC) paste in water was observed. The preformance and microstructure of hardened MKPC were investigated. The results indicated that, because a certain dosage of waterglass has thickening effect on MKPC paste, it may prevent infiltration of water and dissolution of phosphate when fresh MKPC paste was placed in water, at the same time, it will decrease the change of composition in early hydration of MKPC paste. Some waterglass may make the crystal size of hydration products of hardened MKPC smaller and obtain the hardened MKPC with compact structure. It also leads to the obvious decrease of strength loss of hardened MKPC under the erosion of water environment.
