Foaming Agent for Lightweight Concrete Cement Foaming Agent

Cement foaming agent, also known as foaming concrete foaming agent, refers to an admixture that can reduce the surface tension of liquid and generate a large amount of uniform and stable foam for the production of foamed concrete.

Overview of concrete foaming agent:

Cement foaming agent, also known as foaming agent for lightweight concrete, refers to an admixture that can reduce the surface tension of the liquid and generate a large amount of uniform and stable foam for producing foamed concrete. Concrete foaming agent is a substance that can make its aqueous solution generate a large amount of foam when mechanical force is introduced into the air. This kind of substance is a surfactant or a surface-active substance. The essence of the foaming agent is its surface activity.

Applications of concrete foaming agent:

The foaming agent is mainly used in producing foam concrete roofs, roof thermal insulation layers, floor heating foam concrete thermal insulation layers, foam concrete sound insulation, and thermal insulation cushions.

Foaming agents can foam cement, lime, stone powder, fly ash, sand, and other raw materials to make foamed concrete, partition boards, slats, CLC blocks, hollow bricks, solid bricks, thermal pipeline protective covers, roof insulation, hot plate, and other lightweight foam building materials.
1) Make the concrete particles full of bubbles, reduce the substantial density, and reduce the structural load.
2)Improve the performance of concrete, enhance its durability, weathering resistance, corrosion resistance and other properties, while improving the thermal insulation performance of concrete.
3)The insulation layer of ground radiant heating and roof heat insulation.
4)Building inside and outside fill wall blocks, soundproof walls.
5)Municipal pipelines, such as water supply, heating, oil pipelines, etc. insulation, moisture-proof, and anti-corrosion.
6)Construction of greenhouse for plant cultivation and cold storage.
7)Fill the gaps inside the tunnel and the holes in the building.
8)Footpath, sports ground, stadium base laying.



Foam concrete production operation process:

1. Weigh the foaming agent, then add 30 times of water to dilute it to make a foaming liquid;

2. Put the cement, sand, and stones into the mixer in turn, and prepare the concrete slurry;

3. Start the foaming machine and send the foaming liquid into foam through the foam generator;

4. Add the foam into the horizontal mixer according to the predetermined amount and mix it evenly;

5. Send the prepared foaming slurry to the molding machine or mold.



The advantage of CLC foaming agent:

High foaming ratio;

The foam is fine and stable;

Low bleeding;

Good adhesion with cement.




Package of concrete foaming agent:

25 kg/barrel, 200 kg/barrel.
