Donplast® HC3

Cement hydration controlling admixture (Formerly known as Flocrete HC3)

Donplast HC3 is a liquid admixture formulated from selected polymers specially designed to delay the setting time by controlling the hydration process of Portland cement and other cementitious materials. This effect can be used to keep concrete mixes workable up to 3 days.

  • Excellent hydration control for a long time up to 3 days.
  • Excellent slump retention for extended delivery times.
  • Saves transit mixer drums in case of accidents.
  • Reduces the needed amount of wash water to rinse mixer.
  • For wet type shotcrete.
  • For long-distance concrete delivery.
  • High-performance concrete.
  • Concrete wash water stabilization.
  • To avoid setting of concrete in transit mixers in case of an accident.

Donplast HC3 is available in 5 gal (19 litre) containers as well as 275 gal (1,041 litre) and 330 gal (1,249 litre) IBC totes. Bulk supply in tanker trucks is also available upon request.

Donplast HC3 has a minimum shelf life of 12 months from date of manufacture if stored properly in its original unopened packing at temperatures between 35°F and 122°F (2°C and 50°C).

The recommended dosage of Donplast HC3 is between 0.5 to 100 cwt of cementitious materials, including GGBFS, PFA or micro-silica. Actual dosage depends on the desired retardation.

Representative trials should first be conducted to determine the optimum dosage of Donplast HC3 to meet the performance requirements by using the materials and conditions in actual use.

Donplast HC3 complies with the requirements of Specification for Chemical Admixture for Concrete ASTM C494 as a Type B and D admixture.
