What is concrete defoamer

Wholesale gas prices in the Netherlands and the UK have risen 20 percent recently amid concerns about Russian supplies.

The EU plans to cut its dependence on Russian gas by two-thirds this year and stop importing Russian fossil fuels by 2027. Russia exported about 155 billion cubic meters of gas to the EU in 2021.

The US recently said it would try to supply 15bn cubic meters of LNG to the EU this year. U.S. LNG plants are running at full capacity, and analysts say much of the extra gas the U.S. sends to Europe comes from what should have been exported elsewhere.

The German government called Russia "an unreliable energy supplier". Even though the German government claimed that they have been preparing for the situation for a long time that Russia may stop sending gas one day, experts say it is hard for the EU to replace all of Russia's gas exports any time soon.

The supply and prices of many concrete defoamer will continue to be influenced by international situations.

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.

The development of the Russia-Ukraine conflict will continue to dominate the commodity prices such as the concrete defoamer in the future. If the conflict eases or cools, Russia and Ukraine go back to negotiate, commodity prices would fall. However, if the situation between Russia and Ukraine deteriorates further, or evolves into a full-scale war, the price of the concrete defoamer is predicted to see further improvement over the coming days.
