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.

Product Description :
Sodium lignosulphonate (lignosulfonate ) water reducer are mainly for concrete mixture as water-reducing additive. Low dosage, low air content, water reducing rate is high, adapt to most kind of cement. Can confected as concrete early-age strength enhancer, concrete retarder, antifreeze, pumping aids etc. Nearly no precipitate product in the liquor additive which is made from the sodium lignosulphonate and naphthalin-group high-efficiency water reducer .The sodium lignosulphonate is fit for apply to building project, dam project, thruway project etc.
Main performance:
1. Can be applied as common water reducing admixture and built material of series multifunction high-performance water reducing admixtures.
2. Can be adopted as the adhesives in the briquetting procedure in the vertical retort zinc smelters.
3. Can be used as embryo reinforcing agents in the fields of pottery and porcelain and refractory materials. They can increase the fluidity of the slurry and thus to improve the strength of the embryo.
4. In the field of water-coal paste, the sodium lignosulphonate series products can be adopted as the main compound materials.
5. In agriculture, the sodium lignosulphonate series products can be applied as the dispersant agents of pesticides and pelleting adhesives of fertilizers and feedstuffs.
