采用不同细度的一次生石灰和消石灰脱水获得的二次生石灰作为固化剂进行了稳定土强度试验和稳定土XRD分析。结果表明 :利用二次生石灰固化剂固化的稳定土强度较一次生石灰高 2 .0 4倍。其主要作用机理在于比表面积巨大的二次生石灰具有极高的活性 ,加快了石灰和粘土的相互作用和稳定土表层的碳酸化反应速度。所得结果对高强石灰固化剂的研究具有一定的指导意义
Stabilized soil strength test and stabilized earth XRD analysis were carried out by using secondary lime obtained by dehydration of quick lime and hydrated lime with different fineness as curing agent. The results show that the strength of stabilized soil stabilized by secondary lime curing agent is 2.04 times higher than that of primary lime. Its main mechanism lies in its extremely high specific surface area of secondary lime has an extremely high activity, accelerating the interaction of lime and clay and stabilizing the carbonation of the soil surface reaction rate. The results obtained for the study of high-strength lime curing agent has a certain significance
