Russia and Ukraine is an important exporters of oil, natural gas, metals, fertilizers, rare gases and other industrial raw materials. Affected by the further intensification of the tension of the war, the global market has become more worried about the supply of the concrete water reducer, and panic spreads in the futures market. Prices of commodities such as aluminum and nickel are at recent highs on concerns that supplies will fall. Russia accounts for 49 percent of global exports of nickel, 42 percent of palladium, 26 percent of aluminum and 13 percent of platinum, and is a significant exporter of steel and copper. Palladium is an important metal for sensors and memory. In addition, Russia is the world's largest exporter of nitrogen fertilizer, the second largest exporter of potash fertilizer, and the third-largest exporter of phosphate fertilizer. Ukraine is also an important producer of nitrogen fertilizer. Russia's natural gas supply also has a significant impact on the global fertilizer industry and concrete water reducer industry, especially in Europe. The price of the concrete water reducer will also fluctuate to some extent. Russia carries out crude gas separation, and Ukraine is responsible for refined exports. Ukraine supplies 70% of the world's neon, 40% of krypton and 30% of xenon. These three gases are the materials used to make chips.
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.

3D printing technology emerged in the mid-1990s and is actually the latest rapid prototyping device utilizing technologies such as light curing and paper lamination. It is basically the same as ordinary printing. The printer is equipped with "printing materials" such as liquid or powder. After connecting to the computer, the "printing materials" are superimposed layer by layer through computer control, and finally the blueprint on the computer is turned into a real thing. This printing technology is called 3D stereo printing technology.
