When choosing a foaming agent for foamed concrete, you must pay attention to the accuracy of the material name

Definition of lightweight concrete
Lightweight concrete, also known as foam concrete, is to fully foam the foaming agent mechanically through the foaming system of the foaming machine, mix the foam and cement slurry evenly, and then pass the pumping system of the foaming machine for in-situ construction Or mold forming, a new type of lightweight thermal insulation material with a large number of closed pores formed by natural curing. It is a bubble-shaped heat-insulating material, and its outstanding feature is the formation of closed foam cells inside the concrete, which makes the concrete lightweight and heat-insulating; it is also a special variety in aerated concrete, and its pore structure and material properties are close For aerated concrete, the difference between the two is only the difference between the shape of the pores and the means of aerated concrete.

The difference between lightweight concrete and aerated concrete bubbles
The pores of aerated concrete are generally elliptical, while foam concrete is deformed by the effect of capillary pores to form a polyhedron. Aerated concrete uses chemical gas generation, through chemical reactions, gas is generated inside to form pores, lightweight concrete It is through the method of mechanical foaming, first the foaming agent is made into foam, and then the foam is added to cement, magnesite, and gypsum slurry to form a foamed slurry, and then cured by natural curing steam.

Characteristics of lightweight concrete
1. Lightweight
The density is small, and the density level is generally 300-1800kg per cubic meter. For the structure itself, its own weight will be reduced by about 25% compared to ordinary concrete, and for structural members, the structural load-bearing capacity is improved.
2. Good thermal insulation performance
Because lightweight concrete contains a large number of closed small pores, it has good thermal performance, that is, good thermal insulation performance.
3. Good sound insulation and fire resistance
Lightweight concrete is a porous material, so it is also a good sound insulation material. It can be used as a sound insulation layer on floors of buildings, sound insulation boards of highways, and top floors of underground buildings. Lightweight concrete is an inorganic material and will not burn, so it has good fire resistance. When used on buildings, it can improve the fire resistance of buildings.
4. Good overall performance
In addition, it also has the characteristics of low elasticity, good shock absorption, strong waterproof performance, good durability, convenient production and processing, good environmental performance, and convenient construction.

What is foam concrete foaming agent?
The foaming agent used in foamed concrete puts forward technical requirements for concrete foaming. In addition to the large foam generating capacity, it pays special attention to the stability of the foam, the fineness of the foam, and the adaptability of foam and cement and other cementing materials. The narrowly defined foaming agents that can meet this requirement are also very few, and most foaming agents cannot be used in the actual production of foamed concrete. Therefore, the foaming agent for foamed concrete must be a few surfactants or surface-active substances that meet the above technical requirements. Foaming agents are applicable to a wide range of fields, so you must pay attention to the role of the foaming agent you choose, so as to choose the right foaming agent.
