摘要
介绍CMA膨胀土生态改性剂的改性原理,室内改性试验对比研究分析结果表明经CMA改性后的土为非膨胀土,改性后的土体强度高、水稳性好,适用于驻马店至信阳地区的膨胀土改性处理。
The ecological performance theory of CMA-treated expansive soil is introduced.The laboratory test results shows that the soil treated by CMA belongs to non-expansive soil with high strength and water stability,which is used to treat the expansive soil between Zhumadian to Xinyang region.
