Sodium lignosulfonate is first generation concrete admixture.
It is made of wood pulp, a anionic surfactant. Has retarding effect and water reducing effect.
Sodium lingosulfonate is yellow brown powder, can be combined into early strength agent, retarder, antifreeze, pumping agent, combined with naphthalene superplasticizer to liquid admixtures has no precipitate formed.

Sodium lignosulfonate can be used as an admixture for polymers and concrete. It has the advantages of low cost and environmental friendliness.
(1) Cement and concrete water reducer: Lignosulfonate is currently the most widely used water reducer. The use of lignosulfonate as a water reducing agent for cement and concrete can not only greatly improve its fluidity and plasticity, but also greatly reduce harmful pores and significantly enhance compressive strength.
(2) Dispersant, flocculant and corrosion and scale inhibitor: Lignosulfonate is an anionic surfactant with excellent performance, which can be used as dispersant, flocculant, etc.
(3) Oilfield chemicals: Lignosulfonates have a special molecular structure and are widely used in oilfield chemicals. They are often used as surfactants for tertiary oil recovery, drilling fluid treatment agents, and water shutoff agents.
(4) Synthetic resin: Since the 1990s, lignin has often been used as a basic renewable material for synthetic polymer materials, resins and adhesives.
(5) Polymer materials: Lignin and its derivatives can be blended with polyvinyl chloride (PVC), polyethylene (PE), polyvinyl alcohol (PVA) and other olefin polymer materials to improve the stability, strength and Anti-photolysis and other properties.
(6) Agricultural additives: Sodium lignosulfonate can be used not only as a pesticide dispersant, but also as a wetting agent, complexing agent and fertilizer enhancer, and is widely used in all aspects of agriculture.
