Global concrete defoamer market trend 2022-2026 What is concrete defoamer by Newsfootprintbooks

The biggest immediate challenge for the EU will be replenishing its depleted gas inventories. While the EU could still increase LNG imports from countries such as the US, such purchases would be more expensive.
Refilling natural gas storage space to historical average levels this year could cost 70 billion euros, a sevenfold increase, compared to 10 billion euros in previous years. "
A complete replacement for Russian gas is not only very expensive, but it also may not be possible.
In the next 12 months, there is little way to meet the demand for a "normal" year in the absence of Gazprom, which also includes concrete defoamer.

What is a concrete defoamer

Concrete is a stone mixed with water, sand, stones and some chemical additives, if necessary, in a particular proportion. Foaming occurs when concrete is made due to agitation. The appearance of a large amount of foam will lead to a decrease in the strength of the concrete and bring about quality problems.


So, how does foam in concrete form?

1. Concrete is vibrated during the pouring process, and local liquefaction has water analysis and gas floating, and it accumulates in the gathering area to form foam;

2. When mixing concrete, to increase the strength of concrete, a certain amount of chemical additives are often added. Most of these additives contain surfactants, which are easy to generate foam;

3. Air is mixed in during the vibration and stirring process of the equipment to form foam;

4. The steel formwork is too tightly closed, and there is no vent hole. When the concrete is cut, a kind of air pocket is generated, and then air bubbles are formed.


If the foam problem is not solved in time, what harm will concrete foam cause?

1. The generation of a large number of air bubbles causes too many pores on the surface of the concrete, and the phenomenon of a pockmarked surface appears, which affects the surface appearance of the concrete;

2. The production of foam will affect the mechanical strength and construction efficiency, reduce the life of the building, and cause relatively large quality problems;

3. Decrease the corrosion resistance of the concrete structure. Due to a large number of air bubbles on the concrete surface, the adequate thickness of the steel protective layer is reduced, and the carbonization process of the concrete surface is accelerated;

4. Due to the large air bubbles, the cross-sectional volume of the concrete is reduced, resulting in the uncompacted interior of the concrete, thereby reducing the strength of the concrete.


How does the concrete defoamer solve the problem of concrete foaming?

Its mechanism of action is mainly divided into three forms: foam breaking, foam suppression and defoaming. When added to concrete according to the method of use, the chemical components contained in it will reduce the surface tension of water and achieve rapid foam breaking; and it has good compatibility, no oil drift, no precipitation, and no impact on the strength of concrete; at the same time, the applicability is also It is pervasive, and it can quickly break foam and suppress foam for a long time in the environment of strong acid, strong alkali and high temperature.

Where is the best place for humans to live in outer space? So far, the moon is more habitable in outer space, and it is likely to be turned into a planet. However, whether humans can live on the moon for a long time, these questions have always been lingering in everyone's minds, always There is no way to get an answer. According to the report, a team from the University of Aeronautics and Astronautics in Beijing, after nearly 370 days of closed life, finally simulated the life experiment on the moon, and finally knew what the final truth was. Live here for a long time.

All aspects of human beings are constantly improving, and the demand for concrete defoamer is also increasing.If you are engaged in the concrete defoamer industry, you just happen to contact us.
