Russia's insistence on paying for Russian gas in rubles has rattled European countries: Greece held an emergency meeting of suppliers, the Dutch government would urge consumers to use less gas, and the French energy regulator told consumers not to panic. Russian gas meets one-third of Europe's annual energy needs.

Russia said they could expand their demand for ruble payments for other commodities, including oil, grain, fertilizer, coal, and metals, which raised the risk of recession in Europe and the US. 

Moscow is expected to unveil its ruble payment plan in early April, but it said it would not immediately ask buyers to pay for gas in rubles.  

Western countries have said paying in rubles would be a breach of contract, and renegotiation could take months or longer. This uncertainty has pushed commodity market prices higher.

The supply and prices of other commodities like the concrete water reducer could also be affected.

Where Can the Water Reducer be Applied?

The concrete water reducer is suitable for the pumping or normal concrete engineering with a strength grade of C15 to C60 or above. It is especially suitable for concrete projects with high durability, high flow state, high slump protection, high strength, and high appearance quality requirements. It is very beneficial to the preparation of high fluidity concrete, self-compacting concrete, and plain-faced concrete. 

Ordinary water-reducing agents should be used for daily minimum temperature above 5℃ construction of concrete. High efficient water-reducing agents are suitable for daily minimum temperature above 0℃ construction of concrete, and suitable for the preparation of large fluidity concrete, high strength concrete, and steam curing concrete. 

How to Use the Water Reducer?

Polycarboxylate High-performance Water Reducer:

1, The dosage is 0.5%~2.0% of the total weight of the cementitious material, and the commonly used dosage is 0.2% ~ 0.5%. The concrete test should be carried out before use in order to optimize the dosage;

2, It cannot be used with the naphthalene system high-efficient water reducing agent compound, and other admixtures should also be used in advance of concrete compatibility experiment; 

3, Water consumption must be strictly controlled when using, because it affects slump.

4, Pay attention to concrete surface maintenance. 

Naphthalene Series High-efficient Water Reducer:

1, Dosage range: powder: 0.75%-1.5%; liquid: 1.5 to 2.5%. 

2, When using porous aggregate water should first be added and stirred, and then water reducer is added.

3, When the slump is large, the vibration time should not be too long, so that bleeding and stratification could be prevented.

HSB Aliphatic Superplasticizer 

1. Find out the best dosage through experiments. The recommended dosage is 1.5-2%; 

2, Add HSB and water together into concrete.

3. Due to the high water-reduction rate of HSB, a layer of yellow slurry will be secreted on the surface of the concrete before the initial setting, which is a normal phenomenon.  Finished concrete slurry wipe light, the color will be eliminated, or in concrete strength, the color will naturally eliminate, watering and maintenance color will be eliminated faster. It does not affect the inner and surface performance of concrete. 

Suppliers of Concrete Additives

The water reducer with stable quality should be selected. There should be good compatibility between water reducing agent and cement and admixture. When a variety of admixtures with different functions are used in combination, there should be good adaptability between admixtures and between admixtures and cement.

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 water reducer may keep rising.
