摘　　要：以石灰为主要成分,通过掺入其它工业废渣类辅助胶凝材料,研制了一种高效膨胀土固化剂。对膨胀土固化剂的配比进行了优化,并对固化土的主要性质进行了研究。结果表明:经过配比优化后的固化剂固化膨胀土和普通的石灰固化土相比具有强度高,水稳性好,塑性和膨胀性低的特点,且固化效果良好。A new type of high performance expansive soil stabilizer was prepared by adding other industry waste and supplementary cement materials into lime. Research on the optimization of formulas of expensive soil stabilizer and main properties of solidified soil were carried out in this paper. The results showed that the .soil solidified by the expansive soil stabilizer with optimization formula had higher strength, better water stability, lower dilatability and plasticity than ordinary lime solidified soil, and better solidifying effective.
