摘要：
A novel polymer - polyaspartic acid (PASP) resin used as chemical sand-fixing agent (CSFA) was studied in this paper to improve the sand's anti-wind erosion and compressive strength properties. Three laboratory scale simulative aging tests, including freeze-thaw, thermal and ultraviolet (UV) were carried out to evaluate the CSFA properties. It was found that the CSFA could significantly improve specimen compressive strength and anti wind erosion properties. Biodegradability experiments proved that PASP was easy to be biodegraded and was safe to apply. (c) 2006 Elsevier Ltd. All rights reserved.
