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 Concrete strength and shrinkage reducer are still very uncertain.

Description of Concrete strength and shrinkage reducer

1. After adding concrete strength shrinkage enhancer to carbonate cement, it can effectively improve the early and late strength (strength is increased by 5-30%), improve the mold turnover rate, and can also reduce the steam curing temperature or shorten the steam curing time.

2. The coagulant strength-promoting and shrinkage-reducing agent gives the micro-expansion performance to compensate for dry shrinkage, reduce the mixing shrinkage, and improve the crack resistance.

3. Adding a strength-promoting shrink-reducing agent can greatly reduce the amount of Portland cement and reduce the cost of concrete when the early strong friction is not pursued.

4. The dosage of Portland cement can be appropriately reduced after adding concrete strength-enhancing and shrinkage-reducing agent, and low cement and low glue material can still be prepared to reduce the hydration heat release of high-grade and large-volume concrete, and reduce the temperature difference between the center temperature and the surface temperature of the concrete. Reduce the risk of cracking in mass concrete.

5. The strength, impermeability, freeze-thaw resistance, carbonization resistance, and volumetric properties of concrete mixed with strength-promoting shrinkage-reducing agent have been significantly improved.

 Indicators of Concrete strength and shrinkage reducer

The mechanism of Concrete strength and shrinkage reducer

1. With the addition of strength-promoting and shrinkage-reducing agent, calcium sulfoaluminate minerals, calcium sulfate calcined at a higher temperature, high-activity calcium oxide, and Portland cement are compounded and reacted with water to make the calcium aluminate in Portland cement. The aluminum oxide and calcium oxide in the mixed materials such as minerals and slag react to form ettringite hydrated minerals with fast hardness, high strength and slight swelling, so that the potential activity of the mixed materials such as slag can be fully developed. , thereby improving the early and late strength of concrete.

2. The expansive hydration products such as mayvandite and calcium sulfate in the composite system and the organic and inorganic strength-shrinking-promoting components in the strength-promoting and shrinking-reducing agent have the expansion function to compensate for dry shrinkage and improve the crack resistance of concrete. Densification performance and frost resistance, etc.

3. In the composite system concrete, the cohesion is increased due to physical and chemical effects, and segregation and bleeding are avoided.

4. The alkali-free chemical activator accelerates and improves the degree of hydration of cement minerals, thereby improving the early and early strength of concrete.

5. Expansive hydrates such as ettringite and calcium sulfate in the composite system and the shrinkage-reducing components in the strength-promoting shrinkage-reducing agent improve the crack resistance, compactness, frost resistance and impermeability of the mixed soil.

As the Russia-Ukraine conflict continues to develop, there is growing concern 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 strength and shrinkage reducer may keep rising.
