Water Reducing and Accelerator - JK-09NP

Description

JK-09 NP isnaphthalene-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.

Uses

Ø 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.

Advantages

Ø 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.
