Concretum® Q-FLASH 2/20 is the newest generation of rapid-hardening concrete. It is characterised by very rapid hardening, rapid drying and easy handling. Heat of hydration and shrinkage are considerably less than with standard concrete. Production takes place in a concrete plant (ready mixed concrete).

Advantages

  • Easy processing (like standard concrete)
  • Extremely rapid strength development (20 N/mm2 after 1 – 2 hours)
  • Extremely rapid drying (< 4.0 CM-% after 2 – 3 hours)
  • Open time can be adjusted (60 to 120 minutes)
  • Variable consistency: firm to pumpable
  • Low heat of hydration
  • Low shrinkage
  • Temperature range 5 – 30 °C
