Abstract
Sand erosion is a serious problem in the relatively arid and semiarid areas. A novel chemical sand fixing agent (LSUF) synthesized by lignosulfonate graft urea-formaldehyde was introduced in this study. It was made by polymerization of lignin sulfonate, urea and formaldehyde. The newly synthesized product had good water solubility, potentially good biodegradation, and produced no additional pollution. The results showed that the strength test, water-retaining test and wind erosion test of LSUF was better than the sand fixing agent composition by urea-formaldehyde (UF). The LSUF is an environment-friendly products and, it can be considered as an ideal sand fixing agents to control sand erosion in the relatively arid and semiarid areas.
