Description
Sodium lignosulphonate water reducer is 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. 
Featurs / Benefits
Sodium lignosulphonate is an admixture for concrete, which is added in order to reduce the water content in a mixture, or to slow the setting rate of the concrete while retaining the flowing properties of a concrete mixture. 
Sodium lignosulphonate is used to modify the properties of concrete or mortar to make them more suitable to work by hand or for other purposes such as saving mechanical energy.
1. Reduce water content
Rataining the flowing properties of concrete mixture.
Affect fresh properties of concrete by reducing the amount of water used by 8-10%
Accelerate or retard the initial setting time of concrete
Achieve higher concrete density to make the concrete less permeable and have a higher durability.
2. Water reducing and Retarding admixture
Retard the initial setting time for at least an hour
Avoid rapid slump loss and excessive plastic shrinkage                                              Suitable for long haul concrete delivery
3. Increase of slump is different according to its type and dosage. Typical dosage rate is based upon the cementitious material content
