Overview of Foaming Agent
Concrete foaming agent is an admixture that can reduce the surface tension of liquid and produce a large amount of uniform and stable foam, which is used to produce foam concrete. A foaming agent is a surfactant or surface-active substance that produces large amounts of foam when mechanical force is introduced into the air.
1. Concrete foaming agents can produce a large number of evenly distributed foam pores in concrete. These foam pores can improve the sound insulation, heat insulation and impermeability properties of concrete, thereby improving the performance of concrete.
2. It has lower foaming density and better stability, which can ensure the uniformity and stability of foam cells and make the quality of foam concrete more stable.
3. It has good durability and stability, can maintain stable performance under different environmental conditions, and effectively extend the service life of concrete.
4. It has good environmental protection. The foaming agent does not release harmful gases or radioactive substances and is harmless to the environment and human health.
5. It has a wide range of applications and can be used in various types of concrete manufacturing, such as ordinary concrete, lightweight concrete, thermal insulation concrete, etc.

What is Foaming agent?
Re: Foaming agents reduce concrete density to make lightweight concrete or low-strength (flow-fill) concrete, thereby Increasing production.
Characteristics of the best cement faoming agent: optimum machinability and pumpability, little or no bleeding., cntrolled isolation.
How to use CLC foaming agent?
Re: When processed through a foam generator, a solution of blowing agent and water produces a firm white foam with a 20- to 25-fold increase in volume and no foam collapse. Even with cold water, the foam can be easily poured into any mortar mix to make lightweight concrete.
What is the mixture for foam concrete?
Re: Foam concrete mix itself is made of fine sand, cement, water and stabilizing foam. A standard recipe is 2 parts of cement and fine, dry sand to 1 part water and foam generator.
You will want to have a quality foaming machine to get the best results.
What is foam concrete？
Re: Foamed concrete, also known as foam concrete or lightweight concrete, is a material that is mechanically foamed by a foaming machine and mixed with cement slurry. The characteristic of this material is that its internal foam pores are closed, and these foam pores provide lightweight and thermal insulation effects for the concrete. The production process of foamed concrete includes mixing foaming agent, cement, fly ash, stone powder, etc. into organic cement, and then performs cast-in-place construction or mold forming through the pumping system of the foaming machine, and finally completes it through natural curing. It can be used in various occasions such as roof insulation and slope finding, ground insulation cushion, upturned beam foundation pit filling, etc., as an energy-saving material.
How many strength levels does foam concrete have?
Re: There are 11 intensity levels, namely C0.3, C0.5, C1, C2, C3, C4, C5, C7.5, C10, C15 and C20.
Usually C0.3 strength, used in ultra-light insulation roofs, with good thermal conductivity.
C0.5, C1 and C2 are used in general thermal insulation roofs. C3, C4, C5, C7.5, C10, C15, C20, in the cast-in-place construction process, aggregates or heavy aggregates are added, such as fly ash, sand, etc., used in high-strength roofing and highway widening projects. wait.
What is the difference between foam concrete and lightweight aggregate concrete?
Compressive Strength: The compressive strength of lightweight aggregate concrete is generally higher than that of foamed concrete.
Heat transfer coefficient: The heat transfer coefficient of foamed concrete is lower than that of lightweight aggregate concrete.
Density: The density of foamed concrete is usually below 600kg/m³, while the density of lightweight aggregate concrete has a wider range, approximately between 800 and 1400kg/m³.
Type of Aggregate: Foamed concrete typically uses conventional aggregate, while lightweight aggregate concrete may use lightweight mineral aggregate or lightweight polymer aggregate.
Performance characteristics: Lightweight aggregate concrete has the characteristics of light weight, good thermal insulation, and fire resistance due to its lightweight aggregates; foamed concrete has lower density, light weight, good sound insulation, and thermal insulation due to the existence of bubbles. It has strong characteristics, but its mechanical properties are poor, brittle and easy to crack.
Engineering applications: Lightweight aggregate concrete is suitable for construction projects that require light weight and good thermal insulation properties, such as roofs, interior wall filling walls or columns, floor structures, etc.; foamed concrete is mainly used for partition walls, exterior wall filling, floor sound insulation, etc.
