1. Application
For the preparation of large flow concrete, there are cast-in-place concrete and precast components with early and high strength requirements, which have very good use effect, and can comprehensively improve and improve the various properties of concrete. It is widely used in highways, Bridges, DAMS, ports, tunnels, electric power, water conservancy and industrial and civil construction projects, steam cultivation and natural conservation to system components, etc.
It can be used with electro-ionic and non-ionic surfactants. It is resistant to acid, alkali, hard water, salt, diffusion and
protective colloid, and has no paint penetration and foaming. It has affinity for protein and nylon fiber, but has no affinity for cotton and flax fiber.
2. Performance features
(1) In the concrete strength and slump basically the same, can reduce the amount of cement 10-25%.
(2) When the water-cement ratio remains unchanged, the initial slump of concrete can be increased by more than 10cm, and the water reduction rate can reach 15-25%.
(3) For concrete has significant early strength, strengthening effect, its strength increase range of 20-60%.
(4) Improve the workability of concrete, improve concrete physical and mechanical properties.
(5) Good adaptability to all kinds of cement, and other types of concrete admixture compatibility.
(6) Especially suitable for use in the following concrete projects: fluid concrete, plasticized concrete, steamed and raised concrete, impermeable concrete, waterproof concrete, natural curing precast concrete, reinforced and prestressed reinforced concrete, high strength and ultra-high strength concrete.
(7) Concrete slump through the loss of large, half an hour slump loss of nearly 40%.
3. Mixing range
Recommended dosage:
Powder: 0.75 to 1.5%; Liquid: 1.5 to 2.5%.
