PCE Concrete Admixture

Polycarboxylate superplasticizer(PCE) is a kind of high-efficiency water reducer that appeared in the early 1980s. It is mainly used for concrete. PCE concrete admixture belongs to polymer surfactants. Therefore, it can also be used in other paste-like materials, such as gypsum and ceramics, to reduce water content. PCE based admixture generally has a water reduction of more than 25% in concrete and has good compatibility with the base material. Adding the amount of pce admixture into concrete, the slump and expansion loss of the concrete are small, the fluidity is large, and the water retention, cohesiveness, and climate adaptability all perform well.

PCE superplasticizer is an important component in high-performance concrete. In addition to having a high water reduction effect, it can also effectively control the slump loss of concrete, which can largely meet the requirements of concrete durability. At the same time, it also has many outstanding characteristics such as low dosage, good adaptability to admixtures, little impact on dry shrinkage of concrete, no formaldehyde, and environmental protection.

Benefits

The use of pce superplasticizer in the project has great economic and social benefits.

Economic benefits:Due to the use of pce in concrete, the water-to-cement ratio of the concrete is greatly reduced, which provides good conditions for adding a large number of various mineral admixtures in the concrete. The use of a large number of mineral admixtures improves the durability of the concrete, reduces the heat of hydration of the concrete, and enables various performance indicators of the concrete to meet relevant technical requirements. At the same time, the dosage of cement has been greatly reduced, the cost of concrete production has been reduced, and considerable economic benefits have been achieved.

Social benefits:The production process of pce concrete admixture for sale is environmentally friendly and does not produce any waste gas or waste. Through the use of pce admixture and mineral powder and fly ash, the consumption of non-renewable resources is reduced, and the carbon dioxide emissions are reduced. On the other hand, it consumes a large amount of industrial waste such as fly ash and slag powder, zeolite powder, steel slag powder, etc., which reduces environmental pollution, meets the national energy conservation, environmental protection, waste disposal requirements, and achieves significant social benefits.

Performance

A. PCE water-reducing admixture has the characteristics of low dosing and high water reduction. The water-saving rate is 25% to 40%, which is suitable for the preparation of high-strength and high-performance concrete.

B. Adding polycarboxylate pce in concrete, the concrete slump loss over time is small. Conducive to long-distance transportation.

C. It has obvious hardening and reinforcing effects on concrete. 3d strength can be increased by 50 ~ 100%, 7d, 28d strength can be increased by 30-50%, and the strength in the later period has maintained a steady increase.

D. The fresh concrete has good processability, good pumpability, and no segregation.

E. No chlorine, low alkali, no corrosion to steel bars or aggregates.

F. The concrete air content can be adjusted according to the needs of the project.

G. Significantly improve the frost resistance, impermeability, low carbon capacity and shrinkage resistance of concrete. It can significantly extend the life of the concrete.

H. Pce based admixture has good adaptability and can meet a variety of cement varieties. It is especially suitable for high-strength, high-flow, high-performance concrete formulated with active admixtures such as fly ash and slag.

I. PCE chemical is non-toxic, non-polluting during production and safe to health and the environment. Meets current environmental standards for internal and external buildings.

Notes

PCE liquid can be widely used in ordinary concrete and high-performance concrete, especially in early strength high-performance concrete with excellent performance.

PCE concrete admixture can be used for pumped concrete buildings in industrial and civil buildings, hydraulic engineering, ports, transportation, municipal and railway. It can also be used to make special concretes such as high strength, ultra high strength, high impermeability, early strength, self-leveling, and steel fiber types.

The dosage of pce is determined by trial mixing according to the specified concrete mixture.
