The roble had hit a record low after the West imposed sweeping sanctions on Russia for its aggression in Ukraine. Russia's president recently ordered exports of Russian gas to "unfriendly" countries to be settled in robles. The speaker of Russia's upper house of parliament said Moscow was prepared and could shift supplies to markets such as Asia if Europe refused to buy Russian energy.
European countries, which pay mostly in euros, say Russia has no right to reset contracts. The G7 rejected Russia's demand and urged companies not to agree to pay in robles, saying most contracts stipulated payment in euros or dollars. Wholesale gas prices in Europe have risen further recently on concerns about potential supply disruptions.
The Kremlin spokesman said, "According to the March 31 deadline set by Russia's president, we are developing all payment methods to get a simple, understandable, and feasible system for relevant European and international buyers,"
The markets and prices of more commodities like the concrete water reducer would be affected because of the volatile international political situations.
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.
