SYW-7 type air-entraining agent
1. The dosage is 0.004-0.015% of the amount of cementitious material. The amount of rolled concrete can be increased according to design requirements, and the amount of pumped concrete is reduced to 0.003-0.006% of the amount of cementitious material.
2. Adding this product can improve the fluidity and plasticity of concrete, reduce bleeding and segregation, increase the flexural strength by 10%-20%, and improve the durability of concrete.
3. This product has a small amount of mixing and a large number of bubbles introduced into the concrete, which can reduce the surface tension of the solution, produce closed and independent bubbles, high foaming ratio, small bubble spacing and long stability time.
4. This product has strong adaptability to materials and good compatibility with concrete admixtures, which can significantly increase the workability of concrete.
Scope of application
1. It is suitable for concrete structures that require high concrete durability (especially frost resistance), such as hydraulic engineering, port engineering, roads and bridges and other important projects.
2. It is suitable for concrete roads and bridges where deicing salt is spread in the north.
3. It is suitable for concrete projects with high requirements for construction and workability.
Direct addition method, mix this product with other materials evenly, add water and stir.
