AFS稳定细粒土结合料的性能与应用

Properties and Engineering Application of AFS Stabilized Fine-grain Soil Binder

AFS是由石灰、粉煤灰、激活剂配制的一种新型细粒土结合料。本文研究AFS对细粒土和细粒土质砂砾的稳定作用 ,并与水泥、石灰稳定土的强度进行了对比。结果表明AFS稳定土强度优于水泥、石灰稳定土。AFS适应于稳定细粒土 ,也可用于稳定细粒土质砂砾。实际工程应用表明 ,AFS稳定土作道路基层具有良好的工程应用性。

A new type of stabilized fine-grain soil binder named AFS is made of quick lime, fly-ash and activating agent. In this paper the affection of AFS stabilized fine-grain soil and granular fine-grain soil are studied comaparing with lime and cement. The test results indicate that AFS stabilized soil's strength is higher than that stabilized with cement lime. AFS can be used to stabilize soil and granular. The Engineering application indicated that AFS stabilized soil is suitable to build road sub-base course.
