高性能土壤固化剂的制备与性能

为适应滨州地区土壤盐渍土的土质要求,提高固化土壤的强度,以石灰、石膏为主要原料,通过正交试验的方法研究了影响滨州地区土壤的因素,确定了高性能土壤固化剂的最佳配比。对固化剂稳定土与石灰、水泥等稳定土进行对比试验,并初步分析了其固化机理。结果表明:固化剂稳定土的强度高于石灰、水泥等稳定土,且水稳与冻稳系数均大于0．90。

Preparation and Properties of High Performance Soil-Solidified Agent

To improve the strength of the solidified soil, the influencing factors were studied and the optimum blending ratio of high performance soil - solidified agent was determined by means of orthogonal experiment in this paper aiming at soil condition in Binzhou, which is mainly salty soil. The main materials are lime and gypsum. The early strength of the stabilized soil was compared with lime and cement stabilized soil and the solidifying mechanism was analyzed primarily. The result shows that the early strength of the stabilized soil is higher than that of the lime and cement stabilized soil. Furthermore, the coefficients of water resistance and freezing stability are more than 0. 90.
