Calcium Lignosulphonate is a kind of natural anionic surface active agent processed with sulfurous acid pulping waste through advanced production technology. It can work well with other chemicals and produce early strength agent, slow setting agent, antifreeze and pumping agent . It is widely used in various concrete projects such preformed concrete, reinforced concrete and prestressed concrete, especially applicable for commercial concrete, anti-freezing concrete, waterproof concrete, bulk concrete, pumping concrete, with high economic benefit.
