Key technology of polycarboxylic acid water reducing agent application

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 polycarboxylic acid superplasticizer could also be affected.

In recent years, polycarboxylic acid superplasticizer has been widely used in many construction fields.  Modern concrete has high requirements for additional functional additives, so polycarboxylic acid water-reducing agent in the concrete system, it should consider the following key technologies.  

The compatibility technology of polycarboxylic acid series.  Because of the special structure of polycarboxylic acid superplasticizer, it can not be stored and used with other superplasticizers, especially naphthalene superplasticizer.  Need and different type of water reducing agent for alternate use, must be the relevant container for serious cleaning cleaning, prevent cross pollution to affect the quality of concrete.  The adsorption performance of water reducing agent is not the same because of different types of cement, because the polycarboxylic acid water reducing agent is relatively narrow in the compatible range of cement, the incompatible situation is inevitable, so it is necessary to increase its dosage or use different types of cement to effectively solve this problem.

⑵ retarding technology of polycarboxylic acid water-reducing agent.  In the construction process, due to the short retarding time, the use of retarding agent can effectively prolong the plasticity of concrete.  However, the incompatibility of the two should also be considered to avoid the reduction of concrete performance.  

⑶ Gas control.  Polycarboxylic acid water reducing agent entrainment effect is very good, can be used together with defoaming agent, entrainment agent.  The gas content of concrete can be controlled and its workability and durability can be improved by removing the concrete and then introducing it.  

(4) Control of mud content in sand and stone.  The application effect of polycarboxylic acid superplasticizer is also affected by the mud content of sand and stone.  If the mud content in the sand exceeds 2%, the structures between the clay layers will therefore absorb large amounts of water reducing agent molecules, reducing the flow performance of the concrete.  If the mud content is relatively large in the construction process, the anti-clay polycarboxylic acid water-reducing agent should be considered.

Because of the conflict between Russia and Ukraine, there is a shortage of natural gas supply. At the same time, other renewable energy sources cannot produce enough electricity, so electricity prices have soared in many countries of the world. For this reason, I assume the supply and prices of the polycarboxylic acid superplasticizer would keep being influenced by the high energy prices.
