选用具有高强度的新型抗水镁水泥作为基材，引入无机发泡剂，在常温下发泡成型凝结固化至终凝后形成封闭的多孔结构板材，试制出具有一系列优良性能的轻质高强镁水泥墙体材料．Ｘ射线衍射图表明，发泡剂引入后，没有改变抗水镁水泥的相组成．在系统地测定了标准小试样的性能后，选择了适合墙体组成的材料配方制作了标准大试样的测试样品，并对所需的性能进行了测试．借助Ｘ射线衍射图、综合热分析曲线，研究了该材料的相组成及在加热过程中的物理化学变化，并对结果进行了讨论．
High-strength new water-resistant magnesium cement was selected as the substrate, inorganic foaming agent was introduced, foamed at room temperature, coagulated and solidified until final coagulation to form a closed porous structural plate, and a series of excellent performances of light weight and high strength were made. Magnesium cement wall material. The X-ray diffraction pattern shows that the phase composition of the water-resistant magnesium cement was not changed after the blowing agent was introduced. After systematically measuring the performance of the standard small sample, a material sample suitable for the composition of the wall was selected to make a standard large sample test sample, and the required properties were tested. With X-ray diffraction patterns and comprehensive thermal analysis curves, the phase composition and physical and chemical changes in the heating process were studied, and the results were discussed.
