Water-resistant magnesium phosphate cement and application thereof
The invention provides water-resistant magnesium phosphate cement. The water-resistant magnesium phosphate cement comprises the following components: dead burned magnesia, phosphate and mineral waste residues, wherein the molar ratio of magnesium element in the dead burned magnesia to phosphorus element in the phosphate is (4-5):1; the content of the mineral waste residues by mass is 10-30% of the total mass of the magnesium phosphate cement; the mineral waste residues are residues of iron ores obtained after mineral separation and smelting; the water-resistant magnesium phosphate cement provided by the invention not only can improve the early strength but also can maintain the strength for a long time, the permeability is reduced and the water resistance is improved, thereby providing favorable conditions for the improvement of the endurance of the magnesium phosphate cement.
