The U.S. and its allies plan to impose sanctions on more Russian industries and supply chains.
The US government representatives recently visited Europe to consult with allies on strengthening and enforcing sanctions to punish Russia. They also plan to take action to disrupt their critical supply chains.
The US government claims that the sanctions imposed on Russia since the invasion began on February 24 have proved extremely effective, plunging Russia into a financial crisis. The sanctions include a freeze on the Russian central bank's foreign exchange assets, a ban on hard currency transactions by major Russian banks and wealthy individuals, and export restrictions on advanced semiconductors and other technologies. The sanctions have weakened the Russian economy and left the Kremlin with fewer resources.
The volatile international political situations will continue to affect the markets and prices of many commodities like the concrete foaming agent.
Introduction to CLC Concrete Foaming Agent
There are two general cement-based foaming materials, one is chemical foaming, that is, through the chemical reaction of aluminum and other aerating agent and alkali in cement to produce gas; Another is physical foaming, through surfactants and mechanical stirring action to produce gas to join cement foaming. Relatively, chemical foaming is more stable and reliable, and more suitable for large-scale promotion.
CLC Physical Foaming Agent
Clc physical foaming agent or cellular lightweight concrete physical foaming agent is an additive which can reduce liquid surface tension and produce a large number of uniform and stable foam, in order to produce foam agent lightweight concrete.
The foaming agent is a kind of substance that can make its aqueous solution produce a lot of foam when mechanical force is introduced into the air. This kind of substance is the surfactant or surface-active substance. The essence of the foaming agent is its surface activity. Without surface activity, it cannot foam.
CLC Chemical Foaming Agent
Chemical foaming, that is, aluminum and other aerating agent reacts with the cement alkali to produce gas foaming.
Aluminum is a very active metal, which can react with water to replace hydrogen in the effluent and form strong alumina. The surface of aluminum particles exposed to air has been oxidized by oxygen in the air, forming an inert protective film of aluminum oxide, which prevents the contact of aluminum with water.
There is a certain amount of alkaline substances in aerated concrete slurries, such as calcium hydroxide and alumina, which can be dissolved in an alkaline solution to produce metaluminate. When the oxide film on the surface of the aluminum powder is dissolved, the aluminum reacts with water to replace the hydrogen in the effluent and form gelatinous aluminum hydroxide. But it, like alumina, prevents the water from touching the surface of the metal, preventing the reaction from proceeding. But aluminum hydroxide can also dissolve in an alkaline solution to form metaluminate. In this way, in an alkaline solution, the aluminum can continuously react with water to form hydrogen gas until it is used up. And hydrogen gas to approximately spherical bubbles, evenly distributed in the slurry, the slurry volume expansion, hardening to form porous silicate products. The aerating agent used in aerated concrete is mainly active aluminum powder. Of course, the active aluminum powder is specially treated. Because active aluminum powder in the natural environment will occur oxidation and lose activity.
Aerated concrete is a new building wall material made of cement, fly ash, lime, and foaming agent through mixed reaction and steam autoclaved. The pores evenly distributed inside make this material very light, and enable it to block sound, and it also has good heat insulation performance. Most of all, it's made of concrete, so it's very strong. Therefore, aerated concrete has the advantages of lightweight, high strength, heat preservation, sound insulation, and fire prevention.
Precautions When Using the Chemical Foaming Agent:
1. The foaming speed should be appropriate, the quality of concrete will be affected no matter if it is too fast or too slow.
2. The generated hydrogen bubbles should be small in diameter and evenly dispersed. Especially in the full volume of cement slurry pouring mold, it is necessary to disperse evenly to ensure the quality of the pouring mold.
3. The condensation and solidification of cement should not be affected when gas is generated. If the cement setting delays, it will lead to cement strength decline or produce an abnormal cement setting phenomenon.

For Germany, the largest economy in Europe, the impact of the Russian-Ukrainian conflict on the natural gas market is the most obvious. This also exposed the serious dependence of some German industrial enterprises on Russian natural gas. Some analysts pointed out that the instability of natural gas supply has had a big impact on the German economy and threatened its market competitiveness because alternative energy supplies will not be cheap and difficult to come quickly. Increased uncertainty over natural gas supplies is putting enormous pressure on German manufacturers in sectors ranging from steelmaking to chemical concrete foaming agent for the time being, but the market demand for concrete foaming agent in the future will also change with the influence of various external factors.
