摘　　要： 为了解决化学固沙中固结层被风沙掩埋和掏蚀等缺点,提出以沙子为骨料,水玻璃为胶黏剂,在最优条件下制备出强度可达4MPa的多孔固沙砖辅助化学固沙,并且联合植物固沙从根本上治理沙漠化的以沙治沙新观点。还考察了不同因素对材料性能的影响,探讨了水玻璃和AlCl3固化液反应的机理。 According to the existed problems of chemical sand-fixing materials,a new sand-fixing materials（porous sand brick） was designed.Sands was main raw-materials and water glass was used as binder.At optimum conditions,the compressive strength of the obtained porous sand brick was arrived at 4 MPa.Influences of the different factor on the sand brick properties are investigated and the reaction mechanism is also discussed.
