Abstract
This paper aims at analyzing the solidification mechanism of fly ash and cement towards the contaminated soil. The man-made contaminated soil was chosen as the research object, and the curing agent, a mixture of fly ash and cement, was used to solidify it. It is concluded that the soil without the addition of curing agent will produce exposed overhead structures after compression and have lower strength and stability. However, the connection way of the original particles of the soil with fly ash-cement curing agent changes, and its strength is also greatly enhanced. Besides, different curing agents have different impacts on the soil. Therefore, the fly ash-cement curing agent has certain application value in solidifying the contaminated soil.
