PCE superplasticizer is a kind of newest concrete admixture made by a variety of natural polymer materials. It is an environmentally-friendly new building material product. We have many different superplasticizer types.
Next, we will separately understand the characteristics and scope of application of the specific admixture.
Common water-reducing agent:
Water-reducing agent is a concrete admixture that can reduce the water consumption for mixing while maintaining the coagulation slump unchanged.
Its function is to disperse the cement particles after adding the concrete mixture, which can improve its workability, reduce the unit water consumption, and improve the fluidity of the concrete mixture; or reduce the unit cement consumption and save cement.
The scope of application of ordinary water reducing agents:
Especially suitable for the preparation of concrete projects with high durability, high fluidity, high slump retention, high strength and high appearance quality requirements.
It is extremely beneficial for the preparation of high-fluidity concrete, self-compacting concrete and fair-faced concrete.
Early-strength agent:
Early-strength agent refers to an admixture that can increase the early strength of concrete and has no significant effect on the later strength.
The main function of the early strength agent is to accelerate the speed of cement hydration and promote the development of the early strength of concrete.
It not only has the function of early strength, but also has the function of one-definite water reduction enhancement.
Its scope of application is most suitable for construction under low temperature conditions in early winter and early spring.
High-efficiency water reducing agent:
An admixture that can greatly reduce the water consumption of the mixture under basically the same conditions of concrete collapse.
The superplasticizer has a strong dispersing effect on cement, which can effectively improve the fluidity of the cement mixture and the slump of concrete, while drastically reducing water consumption and significantly improving the workability of concrete.
The water reducing agent can greatly reduce the water consumption so as to significantly increase the strength of concrete at various ages. While keeping the strength constant, it can save 10% of cement or even more.
In addition, the ion content of the high-performance water reducing agent is very small, so it does not corrode the steel bars.
It can enhance the impermeability, freeze-thaw resistance and corrosion resistance of concrete, and improve the durability of concrete.
The application range of superplasticizer is in almost all major and key projects in the country, especially in water conservancy, hydropower, hydraulic engineering, offshore engineering, bridges and other projects. Polycarboxylic acid-based water-reducing agents have been widely used.
What we mentioned above are the most common concrete additives in the concrete and building construction process.
