水泥稳定土的材料对强度的影响

Effect of Materials of Cement-Stabilized Soil on Strength

水泥稳定土的强度随剂量的增加而增加,但并不是剂量越大越好。强度还与土的级配有关,改善土的级配,更能提高水泥稳定土的强度。而且改善集料的级配以减少水泥用量是减少水泥稳定土基层裂缝的重要措施之一。不同类型的水泥稳定土,要达到相同的强度,不能规定同样的剂量。

The strength of cement- stabilized soil adds with addition of dosage,but it doesnt mean dosage is more, the strength is better. The strength is also related to soil gradation. Improuing of soil gradation, the strength will be raised even more. Moreover improving the aggregate gradation to reduce cement consumption is one of imporatant measures to lessen crack of the cement -stabilized soil. In order to make different cement -stabilized soil reach same strength,the same dosage cannt be adopted.
