Product Summary:
JK-3 retarder and high range water reducing admixture is used to solve technical problems of plasticity-maintaining, applicable to commercial concrete, high-fluid concrete, high strength and high-performance concrete, retarder, or super-retarder concrete, mass concrete and so on. Using this product can reduce the slump loss of the concrete to achieve the pouring and ensure the quality of project. This product has two kinds of powder and liquid form, using the liquid is converted according to the same effect with solid content.
Homogeneity of Norms:
Item Norm Item Norm
Appearance Powder Lark powder Finesse 0.315mm sieve¡Ü12%
Liquid Brown liquid Ph value 7-9
Liquid proportion 1.2¡À0.02 Chlorine content No
Solid moisture rate ¡Ü10% Foam-breaking time ¡Ü30senconds
Principal Technical Performances:
1. The mixing amount is 0.5-1.2% (powdery) of the cementitious material. 1.5-3.0 % (liquid), the water-reducing rate is 15-32%.
2. The product has a retarding effect; the technical performance norm exceeds the norm of the national retarder and high reducing-water admixture (first class).
3. This product has good adaptability of cement. The plasticity-maintaining effect is clear, the slump loss is minimal.
4. Early strength of concrete and the late strength is security without retarding and plastic effect, concrete¡¯s strength will improve 50 - 80% 3 days, increased by 40 - 70% 7 days, increased 30 - 70 % 28 days. Late strength continued to grow.
5. Can reduce the early heat of hydration of cement, hydration heat peak delay occurred that is conducive to the quality of mass concrete construction.
6. Applicable to the preparation of C50-C80 high strength and high-performance concrete.
7. Applicable to the preparation of a plastic security requirement of commercial concrete, high-fluid concrete, retarder or super-retarder concrete, mass concrete etc.
