Water Reducing and Accelerator

Water reducing 10-15% with low dosage of 1.5-2.5% 10-15% of cement will be reserved prestress concrete -5-30Celsius degree DescriptionJK-09 NP is naphthalene-based non-chloride set-accelerating water-reducing admixture, it significantly accelerates setting time, and reduces the quantity of mixing water necessary to produce concrete of a given consistency, while providing greater economy for a given strength. It increases strengths and significantly improves permeability, workability and finishing characteristics. It complies with GB 8076-2008, GB50119-2003 and ASTM C494, Type E. UsesØ        This product is designed for the constructions requiring earlier strength for normal concrete, steel-reinforced concrete, and pre-stress concrete under normal temperature, low temperature (-5 to 30 degree C).Ø        Widely used in pre-cast & deposit concrete, armored concrete, pre-stressed reinforced concrete and fly-ash-cement concrete. Compatible with Portland cement, normal Portland cement, Portland slag cement, fly-ash cement and Portland pozzolanic cement etc.Ø        Suitable for self-cured concrete and its formulations. It has remarkable effects of water reduction and enhancement, especially at the early stage. The modulus and site utilization can be improved. AdvantagesØ        Accelerating setting time across a wide range of temperatures. Increasing early and ultimate compressive and flexural strengths.Ø        Water reducing 10-15% with low dosage of 1.5-2.5%Ø        After application, all physical properties of concrete can be improved to a certain extent.Ø        10%-15% of cement will be reserved when it is applied as a condition of blending in which collapsibility and strength are fixed forehand. Specifications
