Advantages of Polycarboxylate Superplasticizer

 

1.It has good compatibility with various cement, good slump retention performance of concrete, and prolonged concrete construction time.
The dosage is low, the water reduction rate is high, and the shrinkage is small.

2.Greatly improve the early and late strength of concrete.

3.Low chloride ion content and low alkali content are beneficial to the durability of concrete.

4.The production process is non-polluting and contains no formaldehyde. It conforms to the international standard of ISO14000 environmental protection management and is a green product.

5.With polycarboxylate superplasticizers, more slag or fly ash can be used instead of cement to reduce costs.
This series of products adopts international advanced external circulation spray B (C) oxy plus It is a device and adopts advanced catalytic technology.

Polycarboxylate superplasticizers (PCEs) emerged as one of the most important superplasticizers for concrete due to their superior performance. Compared to other products like polycondensates, they fluidize cement even at low water to cement ratios, require relatively low dosages, and exhibit a long slump retention capability. 

The high dispersing efficacy of PCEs can be ascribed to the nonionic side chains, which stretch out into the pore solution and act as a steric barrier to keep the cement particles apart. Moreover, due to the adsorption of the PCEs, a negative surface charge is induced, which also provokes electrostatic repulsion between cement particles.
