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 Specification Items Specification KR(20%) KR(40%) KR(Pwd) Visual Pale Brown Liquid Pale Brown Liquid Light Yellow Powder Density 1.05?0.02 1.12?0.02 510?10kg/m?
