DENKA NATMIC Z is an calcium aluminate-based powder accelerator for shotcrete. The accelerator is applied where initial rock support is needed or where a permanent lining will be placed.
Quick setting time and very high initial strength achieved through initial ettringite formation
Development of high compressive strength; excellent durability
Good bonding to ground surface; low rebound
Resistant to water leakage in tunnels
