5. Primary usage:

   1) Water reducing rate

     The cement paste flow will be increased with the increase in dosage of lignin sulfonate,and will be up to 173mm ,the water-reducing rate will reach 10% or more.

   2) Water retention

     The product has a good Water retention to the fresh concrete.

   3) Compressive capacity

     The product can improve the compressive strength of concrete.The compressive strength ratio:3d≥150%,7d≥130%.

   4) Retarding action

      Initial setting time and final setting time of cement paste will be extended with the admixture of the product. Initial setting time and final setting time will be extended 153min and 182min respectively when the dosage is 0.4%

   5) Pumping performance

      Mixed in the concrete mixture in the amount of the product will remain basically unchanged concrete slump, the same amount of cement, water reducing concrete strength increases

6. Package & storage

  1) Package  

      Packing in woven bag lined with double-layer plastic film, 25kg per bag

  2) Storage

      Store in a dry ventilated place,long-term storage without deterioration.
