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 agents.
There are three common foaming agents: animal, vegetable, and compound. Vegetable and animal foaming agents are most commonly used.
Advantages and Disadvantages of Various Foaming Agents
For vegetable foaming agents, rosin resin, alkyl sulfur, acid salts, and alkylbenzene sulfonates are the main raw materials. The formulation of vegetable foaming agents is simpler and the cost is lower than other kinds of foaming agents. However, the main defect of vegetable foaming agents is the poor foam stability and low strength.
Animal foaming agents use animal protein as the main raw material, the foam strength and uniformity are better than that of vegetable foaming agents. But it is more expensive. And it has a short shelf life. Especially in the hot summer climate, the progress of the project will be prolonged, and more materials will be needed.
Compound foaming agents are developed by the composite method, which absorbs the advantages of vegetable and animal foaming agents and makes up for the shortcomings of both, so the compound foaming agent is the best choice in actual construction.
Various Composite Method
1. The complementary method
In view of each component having its own advantages, combining multiple components can achieve complementary advantages. For example, some foaming agent has strong foaming ability but is not stable, we can use other types of foaming agents to help them achieve stability. If the foaming agent costs too much, we can compound it with other cheap foaming agents without damaging the overall performance.
2. The coordination method
Sometimes, multiple compounds do not complement each other, but can be synergistic. For example, the performance of the two or three is not good enough in one respect, but when they compound, the synergistic effect could be reached, so that the effect is greatly enhanced. The synergistic effect is the most common technical principle of various admixtures.
3. The synergistic method:
When the effect of some single component foaming agent is not good in a certain aspect, synergistic ingredients can be used to strengthen it, so that it becomes better than inferior.
4. Increase function method:
Some foaming agents have less function and cannot meet the demand of a certain aspect of the product function, which can be solved by the method of admixture.
The compound of lightweight concrete additives is a trend. Because even if the performance of a single variety is excellent, it is impossible to meet more and more stringent technical requirements.

Twitter recently announced that it had reached an agreement with Musk to take full ownership of the company for $54.20 per share, or about $44 billion in cash. After the deal, Twitter will become a privately held company. The deal, which has been unanimously approved by Twitter's board but still requires shareholder and regulatory approvals, is expected to close in 2022.
After Tesla CEO Elon Musk's acquisition of Twitter was finalized, Twitter founder Jack Dorsey sent out a series of six tweets expressing his expectations for Musk.
Dorsey called Twitter his biggest regret, saying, “The idea and service is all that matters to me, and I will do whatever it takes to protect both. Twitter as a company has always been my sole issue and my biggest regret. It has been owned by Wall Street and the ad model. Taking it back from Wall Street is the correct first step.
"In principle, I don't believe anyone should own or run Twitter," Dorsey goes on. He thinks the service is a public good.
He called Musk a "singular solution" to Twitter's problems, "Elon's goal of creating a platform that is" Maximally trusted and inclusive "is the right one." He wrote, "Thank you both for getting the company out of an impossible situation. This is the right path... I believe it with all my heart."
Besides, because of the ever-changing international situation, the supply and prices of international bulk concrete foaming agents are still very uncertain.
