镁基固废再生材料的技术研究

Technical research on magnesium-based solid waste recycling materials

镁基胶凝材料具有可多元改性的特点,与各种材料表面的亲和兼容性较好,力学强度优于钙质胶凝材料,防火性能达A1级。将镁基胶凝材料与固体废弃物资源化再生利用相结合,制备建筑材料,既可解决固废大量堆放占用土地和影响环境的问题,又能节约生产建材消耗的部分资源,具有重要的环境效益和社会效益,实现了环境保护、资源节约、循环经济的多赢。

Magnesium-based cementitious materials have the characteristics of multi-modification, good affinity and compatibility with various material surfaces, better mechanical strength than calcareous cementitious materials, and fire resistance up to A1 level. Combining magnesium-based cementitious materials and solid waste recycling to prepare building materials, it can not only solve the problems of land occupation and environment impact caused by massive stacking of solid wastes, but also save the resources consumed in the production of building materials. It has important environmental and social benefits, and achieves a win-win situation of environmental protection, resource conservation and circular economy.
