Performance Characteristics:
1.the amount of cement can be reduced by 10-25%.
2.When the water-cement ratio remains unchanged, the initial slump of concrete is increased by more than 10cm, and the water reduction rate can reach 15-25%.
3.its strength is increased by 20-60%.
4.Good adaptability to various cements and good compatibility with other types ofconcrete admixtures.
5.Especially suitable for use in the following concrete projects: liquid concrete, plasticized concrete, steam-cured concrete, impermeable concrete, waterproof concrete, natural-curing precast concrete, steel and prestressed reinforced concrete, high-strength ultra-high-strength concrete.
Application:
For the preparation of large-flow concrete, cast-in-place concrete and precast components with early strength and high strength requirements have a good use effect, can comprehensively improve and improve various properties of concrete, and are widely used in highways, bridges, dams, and ports Wharf, tunnel, electric power, water conservancy and industrial and civil construction projects, steam curing and natural curing prefabricated components, etc. On the market, the content of sodium sulfate is divided into high concentration and low concentration.
