As the name suggests, cement hydration is the chemical reaction after mixing cement and water, the powder state into the state of water containing the binding, is our daily use of cement.To enhance some of the properties of cement, I usually add a water reducer during hydration.Below we will understand the concrete water reducer will have what effect on cement hydration?
1. Reduce the surface tension and system viscosity of the solution in the cement slurry;The shear yield stress and plastic viscosity of cement slurry are reduced.
2. The introduction of air into the system to form micro-bubbles is conducive to the flow of fresh concrete;Prolonging the time of early induction of cement hydration.
3. Concrete water reducer can effectively slow down the hydration rate and heat release rate of cement minerals and improve the volume stability of concrete.
4, make the size of crystallization particles of hydration products smaller, so as to improve the compactness of concrete, and then improve the strength of concrete.
Concrete water reducer manufacturers said that the product through adsorption on the cement slurry properties of a series of effects, the performance of the cement has been greatly improved, able to cope with the construction of a variety of cement use requirements.However, it should be noted that the dosage should be measured before adding, so as to avoid unreasonable dosage, resulting in cement performance failure.
