Product introduction of high-efficiency water reducer

High-efficiency water reducer is a concrete admixture with polycarboxylic acid or naphthalene series and aminosulfonate as the main components. It is widely used in concrete engineering to significantly reduce the water consumption of concrete while maintaining or improving its working performance and strength. It is a core material in modern concrete production and has important applications in buildings, bridges, tunnels, roads and other large-scale projects.

Product features

1. Significantly reduce water consumption: reduce water consumption by 20%-30%, optimize water-cement ratio, and improve the density and strength of concrete.
2. Improve workability: enhance the fluidity and collapse resistance of concrete, facilitate construction and casting.
3. Enhance late strength: improve the early strength and final strength of concrete, shorten the construction period, and improve engineering efficiency.
4. Save costs: reduce cement consumption, improve concrete performance, and reduce the total cost of the project.
5. Strong adaptability: suitable for various cements and admixtures, and good compatibility with other concrete admixtures.

Product classification

1. Naphthalene-based high-efficiency water reducer:

• High cost-effective, mainly used for ordinary concrete and high-strength concrete.
• Suitable for medium and low temperature environments, strong durability.

1. Polycarboxylic acid-based high-efficiency water reducer:

• The latest generation of products, with higher water reduction rate and better performance.
• Suitable for high-performance concrete, pumped concrete and ultra-high strength concrete.

1. Aminosulfonate-based water reducer:

• Has strong dispersibility and durability, suitable for concrete construction in complex environments.
