  Polycarboxylate
  KR is a superplasticizer for high performance concrete, high strength concrete. KR has three grades in terms of their solid content.
  1. Solid content 20%(The dosage is 0.8??.1 wt.% of cement)
  2. Solid content 40%(The dosage is 0.8??.1 wt.% of cement)
  3. solid content 98%(powder) (The dosage is 0.8??.1 wt.% of cement, 20% in water)
  KR has some properties
  1. High early strength: Significant increase of early strength and 28d strength
  2. Low slump lose: Great reduction of slump lose
  3. Excellent durability: Reduction of cracking, shrinkage and creep
  4. High water reduction: Water reduction more than 25% according to different application
  5. Environmental friendly products: Non pollution during production
  Package
  1. Liquid product: 200kg drum or 1000kg tank or 20T transport bag
  2. Powder: 25kg plastic bag
