JH-202 type air-entraining water-reducing agent, air-entraining agent, water-reducing agent, air-entraining water-reducing agent
This product is an anionic surfactant, which can significantly reduce the surface tension of concrete and is chlorine-free. , low alkali, water reduction, retardation, small slump loss and other characteristics. Adding this agent can improve the fluidity and plasticity of concrete, reduce bleeding and segregation, and increase the flexural strength by 10%-20%. The thermal diffusion and thermal conductivity of concrete mixed with this agent are reduced, and the volume stability of concrete and the weather resistance of various outdoor structures are improved. Air-entraining water-reducing agents are widely used in water conservancy, bridges, and road concrete, which is beneficial to extending the service life of roads. The most significant advantage of air-entrained concrete is that it greatly improves durability, frost resistance and salt freeze resistance. The appropriate air content for concrete with frost resistance and durability requirements is 3-5%, and the air content should not be too large.
