【摘要】 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更多还原

【Abstract】 The quicklime obtained by burning lime carbonate and the twice quicklime obtained by dehydrating lime hydrate are used to stabilize soil and the compressive strength and XRD of stabilized soil are measured. The results show that the 7 day strength of the stabilized soil with twice quicklime is 2.04 times higher than that with quicklime which is mainly due to the higher specific surface,the reaction activity and carbonate rate of twice quicklime. It is significant that the experiment results given in this paper to the study of the high-strength lime stabilizer.更多还原
