The Biden administration plans to ease sanctions on Venezuelan oil to allow more of the country's crude to reach Europe.
The U.S. will allow European companies still operating in Venezuela to immediately transfer more oil to the continent, while allowing Chevron to negotiate a resumption of operations in Venezuela, according to people familiar with the matter. Venezuela's OPPOSITION, which is backed by the United States, is understood to favor the move. Tight global oil supplies have sent crude and fuel costs soaring, threatening to add to already high inflation. Increasing Venezuelan crude exports would help ease supply constraints while also helping to reduce Europe's dependence on Russian energy.
The US has sought to encourage talks between the Venezuelan government and the US-backed opposition to open the way to free and fair elections by extending a limited license held by Chevron to allow the oil company to maintain its operations in Venezuela and negotiate future operations.
The United States reportedly did not extend a permit to Allow Chevron to drill and sell Venezuelan crude, as the company had hoped.
The license extension will allow Chevron to negotiate with State-run Petroleos de Venezuela SA, with which it has a joint venture. Previously, the company could not directly negotiate with any officials sanctioned by the United States. Chevron has been lobbying the United States to allow it to drill for Venezuelan crude and sell it on world markets to help lower energy prices amid the Russia-Ukraine war.
Affected by the ever-changing international situation, the supply and prices of many commodities like the 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.

According to the bank of Spain's latest forecast data, the average inflation is expected to hit 7.6% in 2022, but the average wage increase for workers in this country is expected to be less than 4% in 2022.
If the Bank of Spain's forecast comes true, the gap between price and wage growth in Spain in a single year will be the largest since 1984.
Prices in Spain rose 9.8% year on year in March 2022 and average wages rose 2.4% year on year, with the Bank of Spain forecasting that the country's inflation rate will improve from July.
Recent changes in the international situation have had a big impact on commodity and energy prices. How the prices of the concrete foaming agent will develop in the future is still uncertain.
