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.

Sodium sulphonate formaldehyde,is chemically synthesized non-air-entraining superplasticizer.Widely used in roads, bridges, dams, ports and docks,tunnels,electricity,water conservancy and civil engineering projects,steaming nd natural preserving components.
1. When the strength and slump are basically the same,the amount of cement can be reduced by 10%-25%.
2. When the water-cement ratio is constant,the initial slump of concrete can be increased by more than 10cm,and the water reduction rate can reach 15%-25%.
3. It has significant early strength and enhancement effect on cockroaches,and its intensity increase range is 20%-60%.
4. It can improve the workability of concrete and improve the physical and mechanical properties of concrete.
5. It has good adaptability to various types of cement and good compatibility with other types of concrete admixtures.
6. Others:In the leather,textile and dye industries,it can also be used as a dispersant.
7. Especially suitable for:fluid concrete,plasticized concrete,steam curing concrete,impervious concrete,waterproof concrete,etc.

Sodium naphthalene sulphonate formaldehyde(snf): snf used as dispersing agent in dyestuff , super plasticizer, high range water reducing agent in construction field, concrete admixtures.
