The invention relates to the technical field of building materials, in particular to water-resistant magnesium phosphate cement and a preparation method thereof.The water-resistant magnesium phosphate cement is prepared from, by weight, 46.6%-61.6% of dead burned magnesium oxide, 18.1%-23.9% of soluble phosphate, 1.7%-2.2% of borax, 0-20.2% of ampullaria gigas shell powder and 12.3%-13.8% of water. By reasonably utilizing the ampullaria gigas shell powder, the problem of flooding of ampullaria gigas is solved, waste is turned into wealth, calcium hydrophosphate is generated through the ampullaria gigas shell powder and residual soluble phosphate in the hardened magnesium phosphate cement, dissolution and filling effect of the soluble phosphate are reduced, and the calcium hydrophosphate is recycled. Therefore, the strength shrinkage phenomenon of the magnesium phosphate cement under the soaking condition is improved, the economic additional value of the ampullaria gigas shell powder is improved, and the damage of the ampullaria gigas to the ecological environment is reduced.
本发明涉及建筑材料技术领域，具体涉及一种耐水型磷酸镁水泥及其制备方法，耐水型磷酸镁水泥包括如下重量百分比的各组分：重烧氧化镁46.6％～61.6％、可溶性磷酸盐18.1％～23.9％、硼砂1.7～2.2％、福寿螺壳粉0～20.2％和水12.3％～13.8％。本发明通过合理利用福寿螺壳粉，解决了福寿螺泛滥的问题从而“变废为宝”，并且通过福寿螺壳粉与硬化的磷酸镁水泥中剩余的可溶性磷酸盐生成磷酸氢钙，减少可溶性磷酸盐的溶出及其填充效应，从而改善浸水条件下磷酸镁水泥的强度倒缩现象，提高了福寿螺壳粉的经济附加值，减小了福寿螺对生态环境的破坏。
