Light foamed soil applied to backfill of subway station foundation pit
The invention provides light foamed soil applied to backfill of a subway station foundation pit, and relates to building materials. The light foamed soil applied to the backfill of the subway station foundation pit is prepared from the following raw materials of cement, kieselguhr, granulated blast-furnace slag, coal ash, water, a water reducing agent, inorganic Aomi fiber, plant fiber, a foaming agent and a micro foaming agent. The light foamed soil provided by the invention is light in weight and high in strength, the whole performance is good, not only can the bearing capacity of a soil body in a soft soil area be met, but also the bearing capacity of an exchange filling foundation on upper load can be met, the load of a special subgrade is reduced, and the subgrade settlement is reduced.
