Characteristic

  • It consists of various compounds such as gluconate and low molecular weight organic acids.

  • Non-toxic and non-corrosive.

  • Generally, the dosage is 0.5%~2.0% (of total solids), which is sensitive to temperature, and the dosage should be increased appropriately with the increase of temperature.

  • It can reduce the consistency of cement slurry and improve the rheology of cement slurry.

  • It can effectively extend the cement paste thickening time.

  • It is generally used in the temperature range of 110℃~210℃ (BHCT).
