BAIJIAN - Third party testing organization
Air entraining and water reducing agent is a highly efficient water reducing agent that is formulated with various surface activities and is a retarder. It is chlorine free、 low alkali、 slow setting、 and has low slump loss. Adding an appropriate amount of air entraining water reducing agent can significantly reduce the surface tension of concrete、 improve its workability、 reduce bleeding and segregation、 and improve its impermeability、 freeze-thaw resistance、 and durability; Adding air entraining and water reducing agents to concrete can produce uniform、 stable、 and non destructible small bubbles、 which are suitable for use in concrete with certain air content requirements such as ports、 docks、 water conservancy projects、 highway pavements、 freeze-thaw resistance、 anti-corrosion、 and anti-seepage projects. Performance index 1: The air entraining and water reducing agent should be determined based on the air content requirement (3-5%)、 and the optimal dosage should be determined after mixing. The powder content is 0.3-0.7%、 and the liquid content is 1.0-1.5%. The water reduction rate can reach 15-20%. 2. The addition of air entraining and water reducing agents reduces the thermal diffusion and thermal conductivity of concrete、 and improves the volume stability of concrete and the durability of various outdoor structures. 3. It can also be used to prepare commercial concrete with freeze-thaw resistance requirements. Before use、 the slump should be determined through testing or adjusted by the manufacturer. 4. Suitable for preparing C30-C50 ordinary concrete、 lean concrete、 hydraulic concrete、 flow concrete、 commercial concrete、 especially for concrete engineering that meets the requirements of freeze-thaw resistance and durability
