Admixtures for ready-mix and precast concrete

MTC® Hardening Accelerator MO5


  • Hardening Accelerator MO 5 (BE) leads to an acceleration of the hydration of the cement and therefore the hardening of the concrete.
  • Hardening Accelerator MO 5 (BE) is chloride free.

Hardening Accelerator MO 5 (BE) enables: - The necessary compression strength of the concrete (in excess of 5 N/mm²) for frost protection within a short period of time dependent on dosage (see guideline below). - The production of flowing concrete and a smooth application with the concrete pump.

Application Area

  • Used for the production of unreinforced concrete for winter application under ambient temperature between 5 to -10°C.
