          Concrete Water Reducer
          
Water reducer is a specifically designed polycarboxylate superplasticizer which owns excellent dispersion performance while maintaining good retention effects due to our cutting-edge processing technique; it is used as a high range water reducing admixture in high performance concrete,high strength concrete,high volume fly ash/slag concrete,cement grouting,and dry mortar.Please feel free to contact with us if you have any needs.
          

          
What role does water reducer play in concrete? According to the academic terminology of water reducing agent, it is called Plasticizer, that is, plasticizer, that is, an admixture that can provide plasticity for fresh concrete.
          

          
The water in the concrete mixture plays two roles, one is used for hydration reaction, this part of water consumption is quite small. It is estimated that all the gelling materials are completely reacted, and the water consumption is only 0.25 times of the total amount of the gelling materials, that is, in the water-binder ratio, only 0.25 water is used for the hydration reaction. This figure is also overestimated because the hydration process is extremely long.
          

          
It is currently known that there are still unhydrated cement particles in the concrete specimens 60 years after molding. Therefore, in the concrete construction process, due to chemical The amount of water consumed by the reaction is extremely small. Most of the water used in concrete is to provide fluidity for the concrete, make the concrete plastic, easy to operate, and form the required structural shape. It is no exaggeration to say that during the construction phase, all concrete water will provide fluidity for the concrete.
