新型高分子固化材料与水泥加固黄土力学性能对比研究

Research on comparison between mechanical behaviors of loess solidified with new polymer material and cement

高分子材料具有传统固化材料所没有的优越性质,其在土加固方面的发展前途远大。利用新型生态环境型高分子材料SH,对我国广泛分布且具有特殊工程性质的黄土进行加固。试验结果表明,用SH固化黄土力学性能好,表现为强度高、耐低温、能抗水。与工程上已应用的水泥黄土进行对比分析,认为SH用量少,价格便宜,固化效果优良,是一种比较理想的高分子黄土加固材料。

It has been noticed that polymeric solidified materials have perfect properties than the traditional ones, so they will have wide prospect. In this paper, an experimental research on the loess, which has wide distribution and special engineering properties, solidified by using the new ecomaterial of SH. The result of the mechanical behavior of loess solidified with SH is clear: the high compressive strength, the good endurance of low temperature and water. Loess-cement has been used in engineering. A comparison between loess solidified with SH and loess-cement is made. Finally, it is concluded that SH is less dosage, cheap price and good solidified effect on loess. SH is an ideal polymeric loess solidified material.
