The US Commerce Secretary has announced that the US will temporarily lift tariffs imposed on Ukraine during the Trump administration to help Ukraine recover its economy and continue to show support for the Russia-Ukraine situation. "For steel mills to remain an economic lifeline for the Ukrainian people, they must be able to export steel," the Commerce Department said in a statement.
The Biden administration will announce the lifting of steel tariffs on Ukraine for one year. Ukraine is a fairly small supplier of U.S. steel, shipping about 218,000 tons in 2019, ranking it 12th among foreign suppliers to the United States, the report said. The U.S. Commerce Department noted that the steel industry is uniquely important to Ukraine's economic strength, with one in 13 people employed in the steel industry.
Affected by the ever-changing international situation, the supply and prices of international bulk concrete foaming agent are still very uncertain.
Foam Concrete Advantages
1. Foam concrete is a lightweight, easy-to-use, and easy-to-finish material. For home improvement projects, such as building decks or other areas on the property, foam concrete may be a wise choice.
2. Foam concrete has high freeze-thaw resistance.
3. It's unlikely to crack or snap easily. Many people use foam concrete in their homes, and structures built with it are very strong.
4. It will not be damaged by welding and grinding as well as cutting or chiseling. Although foam concrete may require some sharp tools (such as a hammer), it can withstand these cuts and grinds well without completely cracking.
5. Foam concrete structure has excellent load dispersion and distribution ability. It is very light and can withstand high load propagation.
6. Foam structure is flexible and easy to use.
7. The use of foam concrete in construction projects such as home improvement projects is very cost-effective and economical. Foam concrete does not have any smell like regular concrete, and its mixture can be mixed with any additives (such as colors, etc.) to create more attractive colors or other patterns that suit people's needs.
8. Foam concrete has high fire resistance.
9. It is well absorbent, meaning that foam concrete will not expand as a result of rain or other moisture that may be present in the surrounding air.
10. Foam concrete is waterproof and can easily withstand water.
11. It does not absorb water when exposed to moisture in the air, so when people use foam concrete to make structures on properties, they can avoid problems like rot and mold.
Foam Concrete Disadvantages
1. Compared with ordinary concrete, the mixing process of foam concrete is difficult.
2. Compared with ordinary cement or concrete, parts of foam concrete are harder to find and therefore more expensive.
3. It is difficult to mix and finish projects without the proper tools or equipment to support them. In addition, the pressure is lower when mixing foam concrete, so special equipment is needed to mix it to an acceptable density.
4. It is difficult to track the strength of the completed structure during the completion phase.
5. Since foam concrete is a mixture of different materials, it depends on each product (such as sand, cement, water, additives, etc.).
6. Due to uneven density during treatment, it may sometimes spread out and cause problems during the finishing or installation phases of these structures.
7. The compressive strength of foam concrete is lower than that of ordinary concrete.
8. Foam concrete is not resistant to acid, oil and grease, and other destructive substances. To protect it from these problems, a protective coating must be applied to the surface of the foam concrete prior to the use or installation stage.
What is Foam Concrete used for?
Foam concrete is fire-resistant and its thermal and acoustic properties make it ideal for a variety of applications, from floor and roof insulation to void filling. In addition, it is good for groove recovery.
Foam Concrete Strength
Foam concrete is a kind of multifunctional material, its strength depends on different cementing materials, cement dosage, mix ratio, water-cement ratio, foam volume, foaming agent, curing method, admixture, etc.
The dry density of foam concrete is between 400-1600kg/m3 and the compressive strength is between 1-25mpa.
Is foam concrete toxic?
Foam concrete does not contain toxic substances.

As the duration of the conflict between Russia and Ukraine grows, its impact on commodities is widening amid the tug-of-war. Recently, European and American sanctions against Russia have been issued one after another. In response, Russia has taken advantage of its role as an important supplier of many energy and commodities, requiring exports of commodities, including energy, grain, metal, and wood, to "unfriendly" countries to be settled in robles. Therefore, it is expected that the price of the concrete foaming agent will continue to increase.
