Concrete water reducer is the biggest application field of sodium lignin sulfonate powder. Sodium lignosulfonate in concrete plays the role of retarder and water-reducing admixture. It is an anion surface-active agent, and its absorption and dispersive action to cement can improve various physical properties of concrete. The use of sodium lignin sulfonate in concrete can reduce water use by more than 13%, improve the workability of concrete, and greatly reduce the initial hydration heat of cement hydration. In addition, it can be compounded with early strength agents, retarders, antifreeze, pumping agent, etc.
