The biggest immediate challenge for the EU will be replenishing its depleted gas inventories. While the EU could still increase LNG imports from countries such as the US, such purchases would be more expensive.
Refilling natural gas storage space to historical average levels this year could cost 70 billion euros, a sevenfold increase, compared to 10 billion euros in previous years. "
A complete replacement for Russian gas is not only very expensive, but it also may not be possible.
In the next 12 months, there is little way to meet the demand for a "normal" year in the absence of Gazprom, which also includes concrete superplasticizer .
Concrete superplasticizer is one of the concrete admixtures which is used most frequently. It can increase the plasticity of concrete and change the strength of concrete.
The essence of superplasticizer: increase the fluidity of concrete
We know, concrete water can provide plasticity for concrete, at this time to add superplasticizer, can make concrete fluidity increase, namely plasticity increase.
But it needs to be clear that if there is no water in the concrete, even if you add more superplasticizer, no matter how to mix, the surface of concrete raw materials cannot be wet, so the friction between particles will still be very high, concrete is a pan of sand, completely do not have plasticity.
On this basis, it can be considered that, in essence, a sufficient amount of water can wet the surface of concrete raw material, and reduce the friction between particles, thus providing plastic properties for concrete; After adding superplasticizer, you can amplify the effect of water, in this sense, adding superplasticizer is equivalent to adding water.
Principle of superplasticizer changing concrete strength
Superplasticizer can amplify the action of concrete water, so as to replace part of concrete water, and play the role of water reduction.
As we know, the strength of concrete is affected by the water-binder ratio, the greater the water-binder ratio, the lower the strength, the smaller the water-binder ratio, the higher the strength. If we add superplasticizer in concrete, reduce water consumption at the same time, keep the fluidity unchanged, in the case of the same amount of cementitious material, the water-binder ratio will decrease, so improve the strength of concrete; If the water is reduced, the amount of cementitious material is reduced at the same time, and the water-binder ratio and fluidity remain unchanged, the cementitious material can be saved.
Concrete superplasticizer is used in this way to change the mix ratio of concrete then to improve concrete strength or save gelling material thereby.

Due to the Russia-Ukraine conflict and the covid-19 pandemic, how will the international situation develop is highly uncertain. It is too difficult to assess its economic impact properly. However, we could see energy prices and commodity prices keep rising and supply chains are disrupted. Therefore, concrete superplasticizer prices are expected to rise in the future.
