Description

JK-06 NP is anaphthalene-based water reducing concrete admixture, with a set retarding effect for concrete in hot temperaturewhich delays concrete setting time. It reduces the heat hydration while delaying the peak of heat hydration and reducing the temperature cracks.

JK-06 NP is compounded by some of retarding composition, stabilizer and reinforcing composition etc. It complies with ASTM C 494 Type D, GB8076-2008 and GB50119-2003.

Uses

  • JK-06 NP is ideal concrete admixtures for all kinds of silicate cement prepared in a variety of architectural concrete, mass concrete, road concrete, port concrete and water conservancy and electricity engineering.
  • Application above 5oC.

Caution

  • Combined with other admixtures must be tested before use.
  • Not be suitable for the cement with the anhydrite or the fluorine stone coagulant.
  • Not apply to steam-curing concrete.
  • Do not excess mixing.

Advantage

  • Reducing 8-12% of water but low dosage from 0.75-1.0%.
  • It has a certain air-entraining performance to increase the impermeability and the antifreeze performance.
  • A good retarding performance, mixed with 1%, it has 1-3h retardation.

Dosage

0.75-1.0% by weight of cement but a limit dosage not over 1.5%, the excess dosage will affect the growth of the early strength of concrete, there may even be a long time without solidification phenomenon.
