This product can improve the slump retention of concrete, reduce concrete bleeding, improve concrete pumping properties, and improve concrete fluidity, segregation resistance and filling properties. It is suitable for preparing all kinds of concrete, especially high-strength, ultra-high-strength, high-fluidity, self-compacting, self-leveling, spraying, and pumping concrete. It can be widely used in key projects such as high-speed railways, subways, highways, water conservancy and electric power projects, ports, large bridges and tunnels, and is also suitable for various types of industrial and civil construction and commercial concrete mixing stations. In addition, this product can also be used in the production of water-reducing agents to improve the performance of various types of water-reducing agents.
This product can replace or partially replace tackifier, pumping agent, water reducing agent and retardant.
Product features:
1. Improve system viscosity: The aqueous solution of this product has good viscosity and consistency. When used in concrete, it can make the concrete have good viscoelasticity, plasticity and toughness, and can effectively improve Concrete is prone to cracks, hollowing, blistering, peeling and other phenomena.
2. Improve workability: This product can improve the fluidity of concrete mixture under low water-binder ratio conditions, while ensuring good cohesion and stability, preventing bleeding and segregation, and making the concrete The structure is more uniform, the pumping process is smoother, and it is less likely to cause blockage and other phenomena.
3. Improved constructability: This product has strong slump-preserving ability and strong adaptability to cement varieties, models and temperatures, and is almost unaffected by changes in external temperature.
4. Good compatibility: This product is a high-molecular biopolymer with strong acid and alkali resistance. It does not react with other materials in the components and is compatible with all commonly used additives including naphthalene, melamine and polycarboxylic acid. All admixtures are compatible.
5. Green: This product is polymerized from high molecular biopolymer and does not cause pollution to the natural environment during production and use.

2. Usage methods and precautions
2.1 According to the concrete design requirements, adjust the water consumption and sand rate through experiments , when the slump, strength, setting time, etc. are all satisfied, determine the amount of anti-segregation agent in the concrete.
2.2 When this product is used in combination with other admixtures, it must be tested before use. Only qualified products and formulas can be used in concrete production.
2.3 When using this product, add the powder and cement directly into the mixer and mix dry for 1 minute. After mixing thoroughly, add water and stir.
2.4 When pouring concrete, strictly follow the construction rules. Just like conventional concrete projects, maintenance must be strengthened according to construction specifications.
2.5 This product is neutral, non-toxic, non-corrosive to steel bars, and non-polluting to the environment but is not edible. When it comes into contact with the human body and eyes, it should be rinsed with clean water as soon as possible. If allergies occur, seek medical attention in time.
