As the European Union tries to reduce its dependence on Russian energy, the Russian president recently said Russia would try to shift its energy exports to the east, adding that there was no way for European countries to give up Russian gas immediately.
Russia supplies about 40 percent of the EU's gas, and western sanctions imposed over the conflict with Ukraine have complicated financing and logistical arrangements for existing agreements, hitting Russian energy exports, the report noted.
Russia has been building closer ties with China and other Asian countries as the European Union debates whether to impose sanctions on Russian gas and oil and member states seek supplies from elsewhere, Reuters said.
"So-called partners from unfriendly countries admit that they cannot survive without Russian energy, including gas," the Russian president said in a televised government meeting. There is no reasonable alternative to Russian gas in Europe right now."
He also said Europe was driving up energy prices and destabilizing markets by talking about cutting off Russia's energy supplies. Russia, which produces about a tenth of the world's oil and a fifth of its natural gas, will need new infrastructure to increase energy supplies to Asia, he said.
He ordered Moscow to submit a plan by June 1, including "the expansion of transport infrastructure to countries in Africa, Latin America, and the Asia-Pacific region".
He also sought to clarify the possibility of integrating two pipelines -- the Sakhalin-Khabarovsk-Vladivostok gas pipeline in the Far East and the "Power of Siberia" gas pipeline to China -- into Russia's unified gas supply system. In theory, connecting these routes to larger gas networks could allow Russia to divert gas from Europe to Asia.
Because of the ever-changing international situation, the supply and prices of international bulk foamed concrete are still very uncertain.
1. Determine the material
The compatibility of cement foaming agents and the foaming machine is the first consideration. Because there is a problem with compatibility between cement foaming agent and cement foaming machine. To understand the compatibility of the cement foaming agent, it is also necessary to determine the reasonable dilution ratio of the foaming agent. If it is the first time using the cement foaming agent, it is recommended to refer to the dilution ratio recommended by the manufacturer and then combine it with your machine test to find the most suitable dilution ratio.
2. Cleaning up the construction site
The first is to clean up the debris and install the water and electricity. Sprinkle cleaning to moisten the surface of the cast-in-place operation; pay attention to the watering must be even and do not have water accumulation.
3. Test whether the foam generator is regular in advance
The test method is to dilute the foaming agent according to a specific ratio, then make foam, and arrange the foam outside the machine to see whether the foam moisture content and the viscosity of the foam are standard.
Whether the bubble is about 1mm, if the moisture content is high, the cells may need to be replaced with steel balls.
4. During the construction of foamed concrete, it should be noted that the slurry of foamed concrete cannot stay, and it should be leveled immediately after pouring to make it stop.
To prevent the foam from breaking and collapsing after re-construction after static stop.
5. Attention should be paid to the influence of air temperature during the construction of foamed concrete. When the air temperature is below 10 degrees, a foaming agent with high stability and suitable for winter application should be selected.
When the air temperature is lower than 5 degrees, it is recommended to use early-strength composite Portland cement in addition to an excellent foaming agent. If conditions permit, a simple plastic greenhouse can be built.
6. Construction in summer requires main moisturizing and maintenance. There are two ways to choose, one is to cover straw curtains, reed mats, sacks, sawdust, wet soil, and wet sand, and the other is to cover with plastic sheets

The resurgence of the global COVID-19 pandemic and the impact of the Russia-Ukraine conflict continued to cause high volatility in commodity prices. Stubbornly high inflation and rising commodity prices are likely to influence each other and thus push each other higher. The price of the foamed concrete may not decrease significantly in the short term.
