Abstract

The research progress in desertification combating at home and abroad, involving inorganic chemical sand-fixing materials, organic chemical sand-fixing materials, and organic-inorganic compound sand-fixing materials, are reviewed. The principle of chemical sand fixation is that the fixation forms a consolidated layer with certain structure and strength in the surface of quicksand. It could prevent the wind erosion and keep the underlying moisture. Chemical sand fixation usually includes five aspects, that is, felting effect, surface coverage effect, hydration, gelifaction, and polymerization. The existing problems and the necessity for developing advanced chemical sand-fixing materials are pointed out. The technical support for the development of advanced chemical sand-fixing materials with the features of low cost, high performance, suitable for the growth of vegetation, environmentally friendly, degradation, large-scale executable is provided.
