Superplasticizer

1. Performance
The superplasticizer has a strong dispersing effect on the cement, which can greatly improve the fluidity of the cement mixture and the slump of the concrete, while greatly reducing the water consumption and significantly improving the workability of the concrete.

However, some superplasticizers will accelerate the slump loss of concrete. When the amount is large (overdose incorporation), it has a slight retarding effect, but it does not delay the growth of the early strength of hardened concrete.

It can greatly reduce the water consumption and thus significantly improve the strength of concrete at various ages. While maintaining a constant value of strength, cement can be saved by 10% or more.

The chloride ion content is small, and 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.

2. Purpose
It is suitable for prefabricated and cast-in-situ reinforced concrete in various industrial and civil construction, water conservancy, transportation, port, municipal and other projects.

It is suitable for high-strength, super-high-strength and medium-strength concrete, as well as concrete that requires early strength, moderate frost resistance, and high fluidity.

Precast concrete components suitable for steam curing process.

It is suitable for use as a water reducing enhancement component (ie master batch) in various composite admixtures.

3. Main varieties
The domestically developed and produced concrete superplasticizers have formed two major categories in the 1990s. One is a synthetic single-component superplasticizer, and the other is a composite multi-component superplasticizer. Single-component superplasticizer, also known as superplasticizer, has a significant effect on reducing and enhancing cement and concrete, but it is often difficult to meet the various requirements of the workability of fresh concrete and the specific performance of hardened concrete, so it is currently used directly The number of projects is gradually decreasing, and a composite superplasticizer is used instead.

Compound superplasticizers are called high-efficiency pumping agents, high-efficiency antifreezes, etc. because they are mixed with other components to meet the requirements of different properties of concrete.

If you want to purchase POLYCARBOXYLATE SUPERPLASTICIZER, you could choose DONGKE groups.
