Light foamed soil applied to backfill of tunnel entrance and exit and production method thereof
The invention provides light foamed soil applied to backfill of a tunnel entrance and exit and a production method of the light foamed soil, and relates to a building material and a production method of the building material. The light foamed soil applied to the backfill of the tunnel entrance and exit is prepared from the following raw materials of cement, silica fume, kieselguhr, coal ash, water, a water reducing agent, an early strength agent, an accelerating agent, aluminite powder, sodium gluconate, 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.
