Description

Technical Field

[0001] The present application relates to the technical field of foam lightweight soil foaming, and in particular to a foam lightweight soil foaming device. Background Art

[0002] Lightweight foam concrete is a new type of lightweight material formed by preparing foam from a foaming agent aqueous solution by physical methods, mixing it with the necessary components of cement-based cementitious materials, water and component aggregates, admixtures, and additives in a certain proportion, and hardening it through physical and chemical actions. This material is similar to cement-stabilized soil. Cement is the main curing agent for its strength formation. External admixtures such as lime, fly ash and early strength agents can also be added. Foamed lightweight soil contains a large number of tiny air bubble groups. Its bulk density can be adjusted within the range of 3 to 12 KN / m3 by adjusting the mix ratio of air bubbles and curing agents in the soil as needed, and the compressive strength range is 0.3 to 5 MPa. This material is light in weight, has good self-stability and durability, and has the characteristics of high fluidity and filling self-compacting.

The main agent is mainly cement, and commonly used ones are volcanic ash cement, ordinary silicate cement, etc., and the auxiliary agents are gypsum powder, silica powder, etc. Bubble stability: The bubbles are composed of dense bubble groups with a diameter of about 30 to 300μ, which have a certain stability. Lightweight and high-strength: Its bulk density is smaller than that of general fill, and its strength and bulk density can be freely adjusted within the scope of engineering application. Low permeability and water absorption: It can reduce the additional stress on the original foundation, reduce the total settlement and uneven settlement, and improve the stability of the foundation.
