The US President recently said the conflict between Russia and Ukraine had driven up the prices of all the world's major food staples, including wheat, corn, barley, oilseeds and edible oils, and that Russia and Ukraine together supplied more than 25% of the world's wheat exports and about 20% of its barley exports.
To address the food shortage, the Biden administration says it plans to increase the number of counties eligible for insurance for double cropping. Double cropping is when farmers grow two different crops a year on the same field.
Under Biden's plan, the number of counties eligible for two-season crop insurance would increase by 681, for a total of 1,935.
The UN has warned that up to 1.7bn people are "highly exposed" to the domino effect of the conflict between Russia and Ukraine on the global food, energy, and financial systems. The agency says conflict could increase hunger in countries where people are already suffering from malnutrition.
Even countries where food is less scarce are being hit by rising prices. U.S. grocery prices rose 1% in April, compared with a 10.8% increase over the past 12 months, the Labor Department said recently.
According to the White House, global food prices have risen nearly 13 percent since the outbreak of the Russia-Ukraine conflict.
Besides, affected by the ever-changing international situation, the supply and prices of international bulk 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).

Because of the conflict between Russia and Ukraine, there is a shortage of natural gas supply. At the same time, other renewable energy sources cannot produce enough electricity, so electricity prices have soared in many countries of the world. For this reason, I assume the supply and prices of the concrete foaming agent would keep being influenced by the high energy prices.
