Concrete Admixture Water Reducing Agent PCE Superplasticizer Powder

Core features

Outstanding water reduction effect with low dosage: This is one of its core advantages. At a conventional dosage of only 0.1%-0.3% of the cementitious material mass, it achieves a high water reduction rate of 25%-45%, enabling the effortless production of ultra-low water-cement ratio concrete (0.25 - 0.35) and facilitating the preparation of high-strength concrete ranging from C80 to C100. Additionally, its low dosage characteristic minimizes interference with other concrete properties from admixtures, enhancing mix stability.

Excellent slump retention: Effectively inhibits rapid slump loss of concrete, with a slump loss of less than 30 mm within one hour. This characteristic is particularly suitable for scenarios such as long-distance transportation of ready-mixed concrete and prolonged construction in large-scale projects, ensuring smooth construction without the need for additional adjustments.

Environmentally friendly and highly compatible: Its production process is pollution-free, free of formaldehyde, and contains less than 0.2% alkaline and chloride ions, effectively preventing alkali-aggregate reactions and reducing the risk of steel corrosion, aligning with green building standards. Moreover, it exhibits excellent compatibility with supplementary cementitious materials such as fly ash, slag, and silica fume, enabling reduced cement usage through blended material combinations, thereby lowering costs and minimizing carbon emissions.

Enhancing the comprehensive performance of concrete: On one hand, reducing water usage improves concrete compaction, lowering porosity by over 50% and achieving a permeability resistance grade of P12-P20. Air-entrained products can also withstand more than 300 freeze-thaw cycles, significantly enhancing durability against freezing, chemical corrosion, and other factors. On the other hand, it markedly boosts both early and late-stage concrete strength, with a 28-day compressive strength ratio exceeding 120%, while also reducing concrete shrinkage and minimizing cracking risks.

Flexible in form and highly adaptable: Available in both liquid and powder forms, the powder variant reduces transportation volume by approximately 70% compared to the liquid, while also preventing molecular chain degradation during storage, ensuring superior stability. By adjusting molecular structures such as side chain density and backbone polarity, customized products with delayed or accelerated curing properties can be developed, suitable for extreme construction climates ranging from -5°C to 40°C.

```Main applications```

Large-scale infrastructure projects: Indispensable in key projects such as high-speed railways, bridges, tunnels, and dams. For instance, in projects like the Beijing-Shanghai High-Speed Railway and the Three Gorges Dam, the concrete mixed with it meets the requirements of high strength, high durability, and long-distance pumping. In marine and offshore structures, its excellent resistance to chloride ion penetration can extend the service life of facilities such as offshore wind turbines.

Specialty Concrete Preparation: As a core admixture for self-compacting concrete, this type of concrete can fill densely reinforced steel or complex formwork without vibration, widely used in scenarios such as subway tunnel sections and reinforcement of densely packed components. It is also suitable for 3D printed concrete, optimizing material rheology and ensuring interlayer bonding precision during printing.

Prefabricated Component Production: In the manufacturing of prefabricated walls, railway sleepers, and prefabricated bridge components, it can accelerate mold demolding speed, enhance surface smoothness of components, reduce subsequent processes such as grinding, and improve production efficiency and quality stability of prefabricated components, meeting the requirements of industrialized building mass production.
