Sodium Lignosulphonate ( lignosulfonate )concrete 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. The Sodium Lignosulphonate is economical one.
The company manages lignosulphonates mainly. such as sodium ligosulphonate, calcium ligosulphonate, ammonium ligosulphonate, magnesium ligosulphonate, lignin series products. and all kinds of new types of Water Repellents and other concrete additives, and produce and supply meticulous chemical products such as magnesium polysilicate and sodium gluconate professionally.

1,Can reduce 10% of water consumption at least ;
2, can improve mixture of the concrete;
3, Compression strength improves by more than 15% equally on 3-28 days;
4, Can reduce the initial stage of the cement heat of hydration by a large margin;
5, Have no function of corroding on the reinforcing bar.
1. 0.2-0.5% of mixing amount in concrete (with cement weight), users can adjust the mixing amount through the test ;
2. Can use after mixed liquid , also can put with cement , aggregate into mixer to use at the same time too, need lengthen time properly;
3. the result is more obvious after mixing with high-efficient naphthalene department water-reducing agent. User can determine the suitable dosage according
to the result that cement variety, aggregate situation, naphthalene department type of water-reducing agent are tested fixing;
1. Strict control to avoid excessive dosage;
2. When the temperature lowers under 5 ?,common concrete projects are not
suitable using the chemical additive independently.
3. Experiment to make sure the dosage before use.
1.packing :It has lastic pellicle inside and is exteriorly packed with plastic woven bag with 25kg net weight per bag.
2.Storage :It shall be stored in a waterproof, rainproof place to avoid agglomeration. If there is agglomeration,
smashing it or dissolving it will not affect using effect.The product is harmless and does not deteriorate in long term.
It's not a flammable and explosive substance.
3. Transportation : It's suitable for both truck transportation and railay transportaion without any limit of
remnant cargo or full truck.
