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.
What is Foam Concrete?
Foam concrete is a highly workable low-density material containing up to 80% air. It is usually self-leveling, self-compacting, and can be pumped. The risk of plastic shrinkage or settlement cracking is obviously lower than that of standard concrete.
Foam Concrete Advantages
Foam concrete is a versatile and practical material that can be customized to a variety of project needs and operating conditions.
1. Pumpable foam concrete - can be pumped over long distances and can be placed by conventional concrete pumps or rotor-stator pumps (often referred to as "worm pumps").
2. Self-compacting and self-leveling - making it ideal for inaccessible troughs where compaction is difficult or impossible. It allows controlled discharge into narrow openings, fully fills void space, including bottom cut pockets, and fully encloses and protects piping.
3. Frost/thawing resistance - High air content makes it frost/thawing resistant and provides excellent heat and sound insulation.
4. The load is dispersed and the settlement risk is negligible
5. Insulation properties - Can be used as a low-density insulator ironing plate
6. Lightweight concrete with high gas content
7. Highly mobile - Easy to place and finish due to a single process installation, requiring only dumping and leveling. Controlled placement rate to ensure applicable to any load characteristics.
Foam Concrete Application
Foam concrete is ideal for filling void Spaces such as abandoned fuel tanks, sewer systems, pipes, and culverts -- especially in hard-to-access areas. It is a recognized medium for repairing road ditches.
Unwanted voids: pipes, service pipes and shafts, sumps
Abandoned structures: culverts and subways, redundant sewers, cellars, and basements
Structural stability: abutment, tunnel stability, embankment
Insulation filler: a leveling layer of low-density insulators used to cover the site
What is the mix for foam concrete?
The foam concrete mixture itself is composed of fine sand, cement, water, and stabilized foam. A standard formula is 2 parts cement and 1 part fine, dry sand, and a foam generator.
How strong is concrete foam?
Foam-based concrete has a dry density of 400 to 1600 kg/m3 (25lb/FT3 to 100lb/FT3) and a 7-day strength of about 1 to 10 N/mm2 (145 to 1450 psi).

Albemarle, the world's largest lithium producer, said it would have to close its plant in Langelsheim, Germany if the EU designated lithium as a hazardous material. The European Commission is currently evaluating a proposal by the European Chemicals Agency (EHCA) to classify lithium carbonate, lithium chloride, and lithium hydroxide as hazardous to human health.
As a result, Albemarle will no longer be able to import lithium chloride, its main raw material, putting its entire plant in Langelsheim at risk of closure, Albemarle chief financial Officer Scott Tozier said. According to Tozier, the plant has annual sales of about $500 million and a forced closure would have a significant impact on Albemarle's operations.
Industry sources said that listing lithium as a hazardous substance would place an additional burden on the concrete foaming agent, please feel free to contact us and send an inquiry.
