The spread of the novel coronavirus is taking a direct hit on the operations of airlines in Asia. About 500,000 flights taking off and landing in mainland China have been canceled since January, according to aviation information company Cerium. Tourists and business trips have plummeted. On the booking website, there are a large number of air tickets for local routes with a price reduction of nearly 90% compared with the original price and only tens of yuan for a one-way trip.
In February, China's aviation industry recorded its largest single-month loss of 24.59 billion yuan, of which airlines lost 20.96 billion yuan.
Data from the Civil Aviation Administration of China showed that in February, the number of passengers traveling by air fell 84.5% year-on-year to 8.34 million.
The stagnation of the Asian aviation industry has brought volatility to concrete foaming agent.
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).

In a recent interview with Izvestia, Russian Federation Council Chairman Matviyenko said that Russia is open to dialogue with the West based on mutual respect, but the opportunity to resume dialogue will only come after the end of special military operations.
Matviyenko also noted that Europe currently lacks politicians who can make independent decisions. She said the EU's strategy to wean itself off Russian energy by 2027 would be costly, with Russia supplying 40 percent of Europe's gas, 27 percent of its oil, and 46 percent of its coal, and was essentially "anti-European" and a "tax" on US global dominance.
On Sweden's and Finland's plans to join NATO, Matviyenko said Russia will take corresponding measures if NATO weapons and equipment appear in the two countries, and Russia is capable of guaranteeing its own security.
Besides, speaking by video at an international conference, Ukraine's minister of agricultural policy and Food, said the country's grain concrete foaming agent are expected to continue to be influenced by international situations.
