Products introduction: 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; Packed in plastic film bag wrapped with plastic woven sack with a net weight of 25kg each
