Gazprom recently said it had completely suspended gas supplies to Bulgarian Gas company and Polish Oil and Gas Company (PGNiG) because it was not being paid in rubles. Russia said it would resume gas supplies after it agreed to pay for them in rubles.
Bulgaria and Poland announced Monday that they have received a notice from Russia to suspend natural gas supplies from Monday.
Russian President Vladimir Putin on March 31 signed a presidential decree to settle gas trade with "unfriendly" countries and regions in rubles. When the new rules took effect on April 1, Presidential press secretary Dmitry Peskov said Russia would not immediately "cut off gas" to Europe, as the cost of gas supplies starting April 1 should be settled in the second half of April or May.
Because of the ever-changing international situation, the supply and prices of international bulk concrete foaming agent are still very uncertain.
Used for anti-electromagnetic radiation function
Foam concrete is an excellent electromagnetic shielding material, which can absorb and eliminate electromagnetic waves. Recently, it began to be used in military and civil buildings with large electromagnetic radiation, and its products are anti-radiation panels, which are in great demand, especially in the military industry.
Used for fire prevention function
1. Fire door
Fire door is a large lifting door set up to cut off the spread of fire in middle and high-rise buildings. it is an indispensable fire prevention structure for building codes, and the development prospect of foam concrete fire door core is very good.
2. Fireproof board
Foamed fireproof board is more fireproof, and the density after foaming is reduced to 800 μ m / m3, which is light and outstanding, and has a great market advantage.
Used for impervious and waterproof function
Closed-cell foam concrete has hydrophobicity, and the dripping water shows lotus leaf dew effect, so its impermeability and waterproof are excellent. This kind of foamed concrete has two major application markets:
1. Building waterproofing and engineering waterproofing
Pouring or laying foam concrete in all parts of the building that need to be waterproof, such as roofs, basements, bathrooms, etc., can save waterproofing agents, achieve permanent waterproofing, and overcome the shortcomings that waterproof coatings are easy to fall off and fail. Using it instead of waterproof material has the advantages of low cost, long service life and more competitive. Foam concrete can be used in waterproof and impermeable aspects of water conservancy projects, such as canals, ponds, towers, swimming pools, underground military projects, tunnels, embankments, fish ponds, artificial lakes, etc., saving all waterproof materials. It is not only a structural material, but also a waterproof material has great advantages.
2. Chloride resistance in underground and underwater engineering
In the soil or water with high chloride ion content, the bases, piles and bridge piers of concrete projects may be damaged by chloride ions. If a protective layer of foam concrete is laid or poured on the outside of these engineering structures, because the foam concrete is impervious, the chloride ion will not be carried by water to erode the concrete.
Used for lightweight density reduction filling function
There are dozens of applications of road backfilling, such as approach bridge filling, soft foundation section filling, abutment back filling, slope subgrade filling, road widening filling, permafrost zone foundation filling, sidewalk filling on both sides of bridge deck, karst cover filling, anti-freezing and thermal insulation pouring, bridge pier foundation pit backfilling and so on. The application in this area is very developed in Japan, and is also widely used in the United States and Europe.
The construction backfill has been applied, such as compensation foundation, top cover of basement and underground square, lightweight floor cushion and so on. Among them, the floor cushion is the largest, which is mainly used for pouring indoor ground pipelines (television, air conditioning, computer, lighting, audio, telephone, etc.). The original use of coke slag cushion has been changed to foam concrete.
Used as lightweight decorative materials and garden products.
The application in this area has high added value, and it is one of the application fields with large profits of foamed concrete, and it has a large market, many products and few producers, so it is very promising.
1. lightweight indoor decorations
The light quality of foam concrete makes it very suitable for the production of imitation gold and silver imitation antique murals, pendants, art decoration boards, interior furnishings and so on. These products were originally made of gypsum with poor strength, and then changed to resin and magnesite, but they are heavy.
2. lightweight decorative tiles for exterior walls
The products that have been developed in this area are: marble or granite facing foam concrete decoration exterior wall hanging board, ceramic tile (3') facing foam concrete hanging board, art concrete facing foam concrete hanging board, aluminum-plastic board facing foam concrete hanging board.
3. lightweight garden products
This kind of products mainly include: imitation wood imitation bamboo grape rack, imitation wood imitation bamboo building components, imitation wood imitation stone open-air table stool, imitation wood imitation bridge stone, imitation wood imitation stone railing, imitation wood imitation stone pond, breathable art high-grade flowerpot, microporous rockery and rockery, landscape lotus lantern that can float on the water surface, simulated Wang lotus and lotus leaves, floating rockery, etc.

With the outbreak of the Russia-Ukraine conflict, the market is increasingly worried about the potential disruption of Russia's energy supply. Geopolitical premiums have pushed up the price of crude oil and natural gas, and the energy price is expected to remain high in the short term. Affected by this, the market price of the concrete foaming agent may continue to rise.
