The European Union is seeking to boost energy cooperation with African countries to help wean them off dependence on Russian gas imports.
Bloomberg said, recently, according to a draft EU file, African countries, especially in western Africa Nigeria, Senegal and Angola have a large untapped liquefied natural gas (LNG), the European Commission will adopt this file about enhanced external energy supply later this month, as part of plans to reduce dependence on Russian energy.
Because of the ever-changing international situation, the supply and prices of international bulk concrete foaming agent are still very uncertain.
The open-cell foam concrete is an excellent sound absorption material, while the closed-cell foam concrete is an excellent sound insulation material.
Materials with an average sound absorption coefficient greater than 0.2 are usually called sound absorption materials. There are two kinds of traditional products: fiber (rock mineral wool board, etc.) and porous (foam and foam glass, etc.). Foam concrete is a new type of porous sound absorption material, and its average sound absorption coefficient is 0.8-1.4, which is a strong sound absorption material and can reach the first or second grade standard. It has great market and competitive advantages in the following aspects.
1. Outdoor sound-absorbing materials (road, railway sound absorption barriers)
Foam concrete outdoor sound absorption material market is mainly the sound absorption barriers on both sides of highways and railways. At present, the sound absorption barriers used in roads are mainly sawdust cement board and foam glass board. The former has a low sound absorption coefficient, which can not meet the needs of high-speed railway, and is not beautiful, while the price of the latter is too high. The foam concrete has good sound absorption performance and can meet the sound absorption requirements of any road, but the price is very low.
2. Sound-absorbing materials of indoor walls
Indoor sound absorption has sound absorption ceiling and sound absorption wall. Foam concrete has a great market advantage in wall sound absorption. Compared with rock mineral wool and other fiber sound absorption board, it does not have the disadvantage of itching all over the body during cutting and installation, and the strength is good, and the price is also low. In the subway wall, this product will have a big market, in large shopping malls, station waiting rooms, theatres, conference halls and other building walls also have a huge market.
3. Sound insulation sandwich composite board (partition sheet)
The existing indoor partition is in the wooden keel on both sides of the installation of 5 "10" paper plasterboard, the wall is empty, not sound insulation, not strong, can not be nailed. The foam concrete composite sound insulation board is 5 inches thick and occupies a small space, the two surfaces are colored decorative layers, and the middle is 4 inches thick foam concrete, which has both isolation and sound insulation effect, and is twice as fast as installation, so it is welcomed by consumers.
1. Used in energy absorption in airport protection.
Foam concrete has very strong impact resistance. Ordinary concrete can be broken with a sledgehammer, but it is difficult to break foam concrete. Making use of its energy absorption, a number of high value-added products have been developed, such as airport safety protection foam block, racing track safety protection foam block, road accident prone zone safety protection foam block and so on. When an aircraft or a car rushes out of control out of the runway or road, it enters the foam block protective belt, which stagnates and protects the aircraft or vehicle intact due to the impact absorption performance of the foam block.
2. Used in shooting and explosion energy absorption protection.
Foam concrete has a good absorption effect on bullet shock wave and explosion shock wave, which can greatly reduce the destructive power of shooting and explosion. In terms of anti-explosion, there are two types of products of development significance and civilian use.

Inflationary pressures on Canadians continue to rise. The consumer-price index rose 6.7% in March from a year earlier, the biggest increase since January 1991, according to the latest figures from Statistics Canada.
On a month-on-month basis, Canada's CPI rose 1.4 percent in March, also accelerating from February's 1.0 percent rise.
Prices in the eight major sectors covered by the statistics continued to rise. The uptrend comes against the backdrop of continued price pressures in the Canadian housing market, widespread supply chain constraints, and geopolitical conflicts, according to CBC. A variety of factors have affected energy, commodity, and agricultural markets. Meanwhile, Canada's employment picture continued to improve in March, with the unemployment rate falling to a record low and the average hourly earnings of employees rising.
Excluding gasoline, Canada's CPI rose 5.5 percent year on year in March. It is also the highest since comparable data began in 1999.
The widespread supply chain constraints and geopolitical conflicts are expected to continue to affect the prices of the concrete foaming agent.
