What exactly is a Cement Foaming Agent?

Concrete/cement foaming agent indicates an admixture that will lessen the surface stress of liquid and produce a considerable amount of uniform and secure foam, which can be employed to produce foam concrete.
The foaming agent is a substance that will make its aqueous solution develop a massive amount of foam when mechanical force is introduced straight into the air. This type of material is a surfactant or surface-active material. The essence of a Foamed concrete is its surface-active effect. Without surface activity, foaming cannot occur, plus it cannot become a foaming agent. Surface activity will be the core of foaming.

The purpose of cement foaming agent

The main purpose of a cement foaming agent would be to promote the foaming of cement paste to make lightweight concrete. Cement foaming agents can produce bubbles through chemical reactions, resulting in the cement slurry to have a large number of pores through the construction process, thereby decreasing the density of concrete and which makes it lightweight, with thermal insulation, heat insulation, sound absorption, and other excellent properties.
Cement foaming agents can also improve the mechanical properties of concrete, enhance its compressive strength and tensile strength, and improve its durability and frost resistance. Additionally, cement foaming agents can also improve the fluidity and plasticity of concrete, making it simpler to construct and shape.

12 features and advantages of foaming agent

1. It has compressive strength and anti-aging properties: Although traditional chemical insulation materials can achieve thermal insulation effects, their compressive strength and anti-aging properties have not been able to meet the requirements. Lightweight foamed cement can totally solve this challenge. , a alternative to traditional insulation materials
2. It is lightweight: its density can reach 200-1600kg/m3, which effectively reduces the load from the building.
3. Good high-temperature resistance: The applicable temperature of foamed cement can reach above 250-300C, as the benzene board will soften and undergo chemical reactions above 75C.
4. Enhance the stability and life from the insulation layer: The foamed cement thermal layer has a high level of stability and anti-aging properties, effectively making sure the indoor floor is flat and not cracked. Its lifespan is 5.10 times that of the benzene board. It is made from perlite particles. A lot more than five times
5. Great thermal insulation: The thermal conductivity is .08w/mk, which can be 20-30 times that of ordinary cement.
6. It has good compressive strength: when the density is 350kg/m3, the compressive strength is 6kg/cm2 in 7 days and 9kg/cm2 in 28 days.
7. Good moisture resistance: There will be no condensation round the warm water pipes during heating, and you will have no splitting in between the layers.
8. Good bonding: The material used in foamed cement is cement, that has an exceptional bond with all the lower and upper layers and definately will not cause hollowing or collapse from the ground.
9. Fast construction speed: each shift can construct 3000-4000 square meters, saving the construction period
10. Good integrity: One-time pouring has no gaps and interruptions and will be combined entirely with all the cast-in-place floor slab and mortar layer to make a whole.
11. It has an anti-permeability effect: Because of the porous and integral nature of foamed cement, the anti-permeability is much more than six times stronger compared to ordinary floor slabs.
12. Fireproof: Foamed cement is definitely an inorganic material (cement) that fails to burn and thus has good fire resistance. When applied to buildings, it could improve the fireproof performance from the building.

Do you know the types of cement foaming agents?

Plant-based cement foaming agent
It utilizes imported high-grade natural plant polymer products as basic materials and it is generated via an accumulation of complicated chain reactions. The product is a pure and clear oily liquid having a light yellow color. It is far from sensitive to difficult water, non-toxic, odor-free, and sediment-free. The PH worth is close to neutral, non-corrosive to cement and steel, and fails to contaminate the setting. The frothing representative is storage-resistant, tough to degrade, has exceptional frothing performance, rich foam, and modest foam stability. Utilizing this frothing agent to make foamed cement has got the highlights of reduced usage, affordability, stability, and high quality. Each barrel of frothing agent (200kg) can generate 500 m2 of foamed cement, so it is commonly found in floor home heating jobs. In roofing insulation projects, building prices could be considerably minimized.
Animal-based cement foaming agent
It uses selected animal (cow, sheep) keratin as the primary raw material and it is made through a series of hydrolysis reactions, heating and dissolving, dilution, filtration, and high-temperature shrinkage. It is produced using imported advanced equipment and also the latest manufacturing technology. Strict quality management is implemented through the production process. The product is a deep brown viscous liquid with low impurity content, light irritating odor, uniform quality, quality of sound consistency, outstanding foaming, and excellent foam stability; this is a new generation of animal-based cement foaming agents. Because of the high surface strength from the foam produced by this foaming agent, the foam is very stable. The bubbles from the foamed cement created using it are in a closed state independent of each other, and there is absolutely no connection between the bubbles. The permeability resistance from the foamed cement products is quite high. At the same density, in contrast to foamed cement created using plant-based foaming agents, it has better sealing as well as heat preservation properties and higher strength.

The applications of cement foaming agent

1. Construction industry

Cement foaming agents are commonly used inside the construction area and are mainly employed to produce lightweight concrete, thermal insulation materials, thermal insulation materials, sound-absorbing materials, etc. Lightweight wet-condensation materials have the benefits of lightweight thermal insulation, sound absorption, etc. These are commonly used in building walls, floors, roofs, partitions, and other components. Thermal insulation materials can be used as building insulation, heat insulation, fire protection, etc. Sound-absorbing materials can be used as building sound insulation and noise reduction.

2. Road industry

Cement foaming agents can also be used in the broad area and are mainly employed to produce lightweight pavement materials, sound insulation materials, waterproof materials, etc. Lightweight pavement materials have the benefits of light, wear resistance, and anti-aging and will reduce road noise and vibration. Sound insulation materials can be used as road sound insulation, noise reduction, etc. Waterproof materials can be used as road waterproofing and anti-seepage.

3. Bridge industry

Cement foaming agents can also be used in the bridge area, mainly employed to produce lightweight bridge decks, sound insulation materials, waterproof materials, etc. Lightweight bridge deck has the benefits of being lightweight, high strength, and good durability, which may detect the weight from the bridge and extend the service life from the bridge. Sound insulation and waterproof materials can be used as bridge sound insulation, waterproofing, etc.
