Curing agent for premixed fluid stabilized soil and preparation and use methods thereof

LIU PENGXIANG

The invention provides a curing agent for premixed fluid stabilized soil and a preparation and use method thereof, and relates to the technical field of civil construction materials. The invention relates to a curing agent for premixed fluid solidified soil. The curing agent comprises the following raw materials: cement, quick lime, slag, fly ash, steel fibers, a water reducer and a penetrant. The preparation method of the curing agent comprises the following steps: crushing the quick lime, the slag and the fly ash until the particle size is 0.5-2mm; and uniformly mixing with other raw materials to obtain the curing agent. The use method of the curing agent comprises the following steps: adding the curing agent into muck, uniformly stirring, then adding water and the composite exciting agent, mixing to obtain slurry, and pouring and backfilling a foundation pit and a fertilizer groove with the slurry. The curing agent has the advantages of being good in curing effect, low in dry shrinkage rate, high in strength and the like, the preparation method and the use method of the curing agent are simple and convenient, and the curing agent has wide application scenes.
