Sodium Lignosulphonate (lignosulfonate) is mainly used as a water - reducing additive in concrete mixtures. It features a low dosage requirement, low air - entraining content, and a high water - reducing rate. It is adaptable to most types of cement. Moreover, it can be formulated into various concrete additives such as early - age strength enhancers, retarders, antifreezes, and pumping aids. The liquid additive made from it has nearly no precipitate.
