Here we will understand the polycarboxylate superplasticizer will have what effect on cement hydration?
1, reduce the surface tension and viscosity of the solution in the cement slurry; The shear yield stress and plastic viscosity of cement slurry are reduced.
2. Introducing air into the system to form micro bubbles, which is conducive to the flow of freshly mixed concrete; Prolonging the early period of cement hydration induction.
3, polycarboxylate superplasticizer can effectively slow down the hydration rate and heat release rate of cement minerals, improve the volume stability of concrete.
4, make the crystallization particle size of hydration products smaller, so as to improve the compactness of concrete, and then improve the strength of concrete.
polycarboxylate superplasticizer manufacturers said that the product through the adsorption of a series of effects on the nature of the cement slurry, the performance of cement has been greatly improved, to respond to the construction of a variety of cement use requirements. But we should pay attention to the dose of experimental measurement before adding, so as not to mix unreasonable, resulting in cement performance failure.
