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.
2. main performance
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.
3. operation methods :
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;
