product use
1. Good bubble structure, small bubble radius, high frost resistance index, used for high durability of concrete structures, such as dams, high-grade highways, thermal power station cooling towers, pool hydraulic, ports, etc.
2. Concrete roads and bridges sprinkled with deicing salt.
3, high and easy concrete works.
4. Pumping concrete.
Main Performance
1. Adding AH series air-entraining agent can improve the slump, fluidity and plasticity of concrete.
2, reduce concrete bleeding and segregation, improve the homogeneity of concrete.
3. AH series air-entraining agent has low elastic modulus, small rigidity and good flexibility.
4. The thermal diffusion and conductivity of concrete are reduced, which improves the volume stability of concrete, enhances the weather resistance of field structures, and prolongs the service life of road concrete.
5, greatly improve the concrete frost resistance, salt resistance, impermeability, resistance to sulfate erosion and alkali aggregate reaction performance.
technical features
1. AH series air entraining agent is added into the mixer together with cement, sand and stone, and the mixing time needs to be extended for 1-2 minutes.
2, construction engineering concrete content should be selected low limit, hydraulic concrete content should be selected high limit.
3. For concrete with high freeze-thaw resistance and winter construction concrete, the content shall be determined through tests according to the requirements of concrete air content.
4, air-entraining agent can also be prepared for use, but must be fully dissolved.
5, air intake by the preparation of concrete materials and preparation of operating environment temperature, it must try to keep stable in order to control the air content fluctuations.
6, high frequency vibration does not exceed 20 seconds.
