Key technology of polycarboxylic acid water reducing agent application

Now China has become a powerful country in science and technology, but do you know how powerful China's technology is? The manned space station alone is not enough, and now it has successfully broken through the key technology of nuclear fusion, even leading the world by 15 years. Does this mean that China is not far from the artificial sun? It turned out that the fully superconducting tokamak nuclear fusion experimental device developed by China at the Hefei Research Institute of the Chinese Academy of Sciences successfully achieved a record of 101 seconds of continuous operation at 120 million degrees Celsius, and broke the world record. Compared with the previous record in South Korea, China has time has been directly extended by 5 times, and it seems that we are one step closer to the practical stage of artificial sun.
The success of nuclear fusion technology will lead to the development of polycarboxylic acid superplasticizer.

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.

Russia is a major supplier of industrial metals such as nickel, aluminium and palladium. Russia and Ukraine are both major wheat exporters, and Russia and Belarus produce large amounts of potash, an input to fertiliser. The price and market of the polycarboxylic acid superplasticizer will fluctuate under its influence. Prices of these goods have been rising since 2022 and are now likely to rise further because of the Russia-Ukraine conflict.
