Global concrete foaming agent market trend 2022-2029 Influence of Concrete Foaming Agent on Foam Concrete (2) by Newsexpost-news

For billionaires, the new crown epidemic is like a 'gold rush'! The Deutsche Presse-Agentur said on the 17th that in 2022, the wealth held by the world's top ten richest people will jump from $700 billion to $1.5 trillion, an average daily increase of $1.3 billion, an increase that exceeds the past 14 years. These 10 people The wealth held by the world’s poorest 3.1 billion people is six times greater than that of the world’s poorest 3.1 billion people. The 10 richest Germans have increased their assets from the equivalent of about 125 billion euros to about 223 billion euros since the start of the Covid-19 pandemic, An increase of about 78%. This wealth is roughly equivalent to the total wealth of the poorest 40% of the population, or 33 million Germans.
In the future, demand for concrete foaming agent will grow as fast as the wealth of the rich during the pandemic.

3. The larger the bubble diameter, the better, should be more than 1mm 

The pore diameter should be the same as the bubble diameter. Some experts misleading the pursuit of a small foam aperture of 0.1mm, in fact, because of physical foaming if the bubble diameter is large, the stability of the foam cannot be made of foam concrete. The same raw material and formula, the same equipment and technology, just change the bubble diameter, the compressive strength of 1mm bubble diameter of foam concrete, then 0.1mm bubble diameter of foam concrete, at least 20% higher. Therefore, it is wrong to pursue a bubble diameter of more than 0.1mm, which should be corrected in the production of foamed concrete.

 

4. The lower the foam bleeding rate, the better. Avoid using milk foam.

According to the size of water content, foam is divided into milk foam with more water and sponge foam with more water. Among them, lacteal foam is unqualified inferior foam and cannot be used.

After the foam is made, it gradually secretes water. Its secreting water includes two parts: 

Bleeding of foam liquid film. This water is secreted from the liquid membrane, which is secreted by the liquid membrane under the combined action of gravity drainage, surface tension drainage, and liquid membrane damage drainage. The thicker the liquid film of foam is, the larger the bleeding is. The faster the bubble burst, the more bleeding.

Water between bubbles. This is the water that didn't form the bubble film. The worse the foaming agent and foaming machine’s foaming performance, the more water between bubbles cannot form foam liquid film. They're essentially water that doesn't bubble.


When the foam is bleeding at a high rate, it becomes as thin as float juice, sloshing around and not piling up, and there's a lot of water in the foam. When this foam is added to the cement slurry, the cement slurry becomes very thin, and the foam is very little, the volume of the slurry is small, and the resulting foam concrete density is very high, not technical requirements. 

 

Therefore, latex foam should not be used. The appearance of a technically acceptable foam should be a spongy, compact bubble, piled up like white clouds, like bouncing cotton, and not sloshing. This foam has very little water content. This shows that its foam liquid film is small, the foam is not easy to burst, there is little water between the bubbles, and the amount of bubbles is large, accounting for most of the volume of bubbles. It should be emphasized here that the spongy foam must be a small bubble with a diameter of less than 1mm, rather than a few millimeters, or even dozens of millimeters. Bullae are easy to pile up, also like white clouds, but because of the large diameter of the bullae, also unqualified. 

 

The low secretion of foam is mainly to ensure the number of bubbles in the foam and the porosity of foamed concrete, that is, to ensure the density of foamed concrete. 

 

5. The foam has no side effects on cementitious materials 

The cementitious material is the main source of strength of foamed concrete, the addition of foam cannot affect its cementitious property, that is, there is no negative cementitious effect. Not every bubble can achieve this.

In the long-term test, we discover a lot of foam to cement, magnesite, gesso of gelling have hindrance, can reduce the strength of foam concrete, sometimes even from beginning to end the concrete after hardening loses strength basically, resemble a dish scatters sand.  The stability of these foams is very good, several hours do not disappear, the appearance of sponge, bleeding is very low, dense, and uniform, all aspects meet the technical requirements, but are not compatible with the gel material, so cannot be used for production. This means that foams that are otherwise qualified, such as affecting strength, are ultimately not technically qualified.

Due to the Russia-Ukraine conflict and the covid-19 pandemic, how will the international situation develop is highly uncertain. It is too difficult to assess its economic impact properly. However, we could see energy prices and commodity prices keep rising and supply chains are disrupted. Therefore, concrete foaming agent prices are expected to rise in the future.
