TamShot 90AF
Overview
TamShot 90AF is commonly used for wet mix sprayed concrete processes in the tunnelling and mining industry. The product is applied where initial ground support is needed or where a permanent lining has been designed (single shell tunnel lining).
TamShot 90AF is a high-performance quick-setting liquid set accelrators for sprayed concrete applications.
TamShot 90AF may also be used to accelerate cementitious-based grouts for TBM tunnel lining backfilling and ground stabilization works.
By adjusting the dosage, setting times and rebound can be reduced providing a safe and efficient work environment.
Fast setting times and continued high early-age strength gain allows for spraying in thicker layers.
Key specification
