Polycarboxylate Superplasticizer Liquid (PCE Liquid), a third-generation high-performance water reducer, is widely used in construction and engineering due to its strong designability in molecular structure, high water reduction efficiency, and excellent environmental friendliness.
Its application covers the traditional field of architecture and demonstrates irreplaceable value in complex scenarios such as super high-rise buildings, cross-sea bridges and nuclear power projects.
PCE Liquid is widely used in producing ready-mixed concrete, especially concrete requiring high strength and durability.
In the production of ready-mixed concrete, polycarboxylate superplasticizers can improve the workability of concrete, making it denser and more uniform and enhancing its strength and durability. PCE liquid precisely regulates the microstructure inside the concrete, helping to produce concrete that meets such high standard requirements and laying a solid foundation for the stability of buildings.
Used for special concrete that requires high strength, impermeability, frost resistance, and other properties (such as self-compacting concrete, early strength concrete, etc.).
Self-compacting concrete requires filling complex molds and uniformly compacting them without vibration, relying on its own gravity. Polycarboxylate superplasticizer liquid endows concrete with good fluidity and anti-segregation properties, making it easy to meet the special requirements of self-compacting.
For early-strength concrete, in some construction projects with tight schedules, it is necessary for the concrete to quickly reach high strength in a short period so that subsequent construction processes can be carried out promptly.
Polycarboxylate superplasticizer liquid can effectively promote the hydration reaction process of cement, significantly improve the early strength while ensuring the workability of concrete, and greatly meet the performance requirements of this type of special concrete.
Improve the performance of concrete in projects such as bridges, underground engineering, and high-rise buildings.
In bridge construction, the structure is exposed to the natural environment for a long time. It is subjected to various factors such as vehicle loads, climate change, and wind and rain erosion. Polycarboxylate water-reducing agent liquid enhances the strength, impermeability, and durability of concrete, enabling bridge concrete to better resist these adverse factors and extend the service life of bridges.
In underground engineering, such as subway tunnels, underground parking lots, etc., concrete needs good impermeability to prevent groundwater leakage. Polycarboxylate superplasticizer liquid can optimize the pore structure of concrete, reduce porosity, significantly improve the impermeability of concrete, and ensure the safe operation of underground engineering.
In high-rise buildings, due to the increase in building height, there are extremely high requirements for concrete strength and pumping performance. Polycarboxylate water-reducing agent liquid can not only improve the stability of concrete and meet the structural bearing capacity requirements of high-rise buildings but also improve the fluidity and pumping performance of concrete, enabling it to be smoothly transported to high-altitude work surfaces and ensuring the construction quality and progress of high-rise buildings.
PCE Liquid can significantly reduce the water-cement ratio of concrete and improve its strength. By reducing the amount of water used, the fluidity of concrete is maintained while enhancing its compactness and strength.
The water reduction rate of polycarboxylate liquid water reducer can reach 35-40%, far exceeding that of naphthalene-based (15-20%) and lignin-based (10-15%) water reducers.
PCE can reduce the water-cement ratio from 0.5 to 0.3 and increase compressive strength by 40-60%
In general, under the same mix ratio conditions, the 28-day compressive strength of concrete using polycarboxylate superplasticizer liquid can be increased by 20% -30% compared to when it is not used, providing a strong guarantee for the construction of high-strength concrete structures.
PCE Liquid can improve the internal structure of concrete and reduce pores and cracks, thereby enhancing impermeability, frost resistance, and durability, enabling concrete to perform well in harsh environments.
Measured by the impermeability level, the use of polycarboxylate superplasticizer liquid can increase the impermeability level of concrete by 2-3 levels, effectively resisting the invasion of water, harmful gases, and corrosive media.
In terms of frost resistance, due to the improvement of the internal structure of concrete, its ability to resist freeze-thaw cycle damage is enhanced.
The rapid freezing test (GB/T 50082) shows that the mass loss after 300 cycles is less than 3%, far exceeding the F150 standard.
PCE Liquid has the characteristics of low toxicity and no pollution, which meets the requirements of modern building environmental protection. Reducing water usage can also save water resources, reduce energy consumption, and contribute to the sustainable use of resources.
Carbon reduction: Reduce cement consumption by 80-100 kg per cubic meter of concrete and decrease CO₂ emissions by 10-15%.
By improving the workability of concrete, polycarboxylate superplasticizer liquid makes concrete easier to construct and form, thereby increasing construction efficiency. Because the setting time of concrete can be reasonably controlled by adjusting the dosage of polycarboxylate superplasticizer liquid, construction personnel can flexibly arrange the construction schedule according to the project’s actual situation. This efficient construction performance significantly shortens the project cycle.
Construction efficiency: pumping speed increased by 50%, and template turnover rate doubled.
Construction efficiency: pumping speed increased by 50%, and template turnover rate doubled.
Suitable for different concrete ratios and production environments, it can be compatible with other building materials such as cement, mineral powder, etc., ensuring that the comprehensive performance of concrete is not affected.
For example, when using mineral powder as an admixture, polycarboxylate superplasticizer liquid can promote mineral powder activation and improve concrete’s later strength and durability. Its excellent compatibility ensures that concrete achieves stable and comprehensive performance under different raw materials and production conditions.
These advantages make polycarboxylate superplasticizer liquid one of the indispensable materials in modern construction, especially in the current continuous growth of demand for high-performance, green and environmentally friendly building materials. Polycarboxylate superplasticizer liquid will play a more critical role in the construction and engineering fields, promoting the continuous development of the industry.
