More Information
Summary:The invention relates to a curing agent for curing soil. The curing agent is prepared from the following raw materials in percentage by mass: 2 to 5 percent of calcium silicate, 3 to 5 percent of limestone, 15 to 30 percent of gypsum, 0 to 10 percent of coking desulfurization and denitrification ash and 65 to 80 percent of slag powder. An application method of the curing agent for curing the soilcomprises the steps that the curing agent and the soil are mixed according to the proportion of 1: 4-15, and 10%-30% of water is added for compaction and solidification. The curing agent and soil components are subjected to ion adsorption and exchange, so that the surface electric quantity of soil micelles is reduced, the thickness of double electric layers of the soil micelles is reduced, and soil particles tend to be condensed; new substances are generated through chemical reaction, so that the linkage among soil particles is enhanced; the volume of a reaction product is expanded, and poresamong soil particles are i
