Application technical requirements

The appropriate dosage of this product needs to be determined according to the gas content requirements (3-5%). The range is 0.3-0.7% for powder, 1.0-1.5% for liquid, and the water reduction rate can reach 13-20%.

Incorporation of this product into concrete reduces thermal diffusion and thermal conductivity, and improves the volume stability of concrete and the durability of various outdoor structures.

It can also be used to prepare commercial concrete with freeze-thaw resistance requirements. Before use, test to determine the slump loss or require the manufacturer to adjust.

Suitable for preparing C30~C50 ordinary concrete, lean concrete, hydraulic concrete, fluid concrete, commercial concrete, especially concrete projects that require freeze-thaw durability.

Please follow the regulations in the "Technical Specifications for Application of Concrete Admixtures".

Add cement or water into the mixture according to the specified dosage and stir. It is advisable to use mechanical stirring.

Pay attention to maintenance work during construction. Concrete physical properties
