The present invention relates to a chemical admixture for concrete, with a polymer of acrylic acid, fructose polyallyl ether, D-fructose-1,6-diphosphate trisodium salt, methyl methacrylate-based polymer, air entraining agent and water It is characterized by being made. The concrete chemical admixture can increase the workability and durability of concrete by securing stable viscosity enhancement, bonding property, emulsification stability and dispersibility in a range that does not affect concrete properties depending on the properties of the composition. By further including by-products of the petrochemical industry in the chemical admixture, there is an effect that can solve the secondary environmental pollution problems caused by the increase in the production cost of the manufacturing process due to incineration, which is the main treatment method of waste. |
