TamShot 80AF
Overview
TamShot 80AF is commonly used for wet mix shotcrete processes in the tunnelling and mining industry. The product is applied where initial rock support is needed or where a permanent lining has been designed (single shell tunnel lining).
TamShot 80AF is a high-performance quick-setting liquid additive for sprayed concrete applications.
By adjusting the dosage, setting times and rebound can be positively influenced without risking a caustic work environment due to its low alkali content (< 1%).
High final compressive strength development after 28 days and excellent long-term durability
Key specification
- Sprayed concrete quick set accelerator
- Alkali-Free Accelerator for Sprayed Concrete Applications
Key benefits
