在一些水泥加固软土地基的工程中，发现有机质对加固效果有影响。因此，加入额外的外加剂以加速水泥的反应并改善稳定效果。本研究将不同种类的外加剂与水泥混合使用，以稳定高有机质含量的软土。进行了直剪试验和无侧限压缩试验，得到了不同条件下的力学指标。测定了各样品中有机质的总量和组成。试验结果表明，外加剂的掺入对水泥土的性能有一定的改善作用，不同外加剂的作用不同。
In some projects where cement is used to stabilize soft soil foundations, it is found that the organic matter influences the stabilization effect. As a consequence, extra admixtures are added to accelerate the reactions of cement and improve the stabilization effect. In this study, different kinds of extra admixtures were used with cement to stabilize a soft soil with a high organic content. Direct shear and unconfined compression tests were undertaken and the mechanical indices in different conditions obtained. The total amount and components of the organic matter in every sample were also determined. The results show that the addition of extra admixtures improves the properties of cement-stabilized soils and that different extra admixtures play a different role.
