DURABILITY OF DRY-MIX SHOTCRETE

Dry-mix shotcrete specimens sawed from field-shot panels were tested for freeze-thaw durability, resistance to chloride-ion penetration, compressive strength, characteristics of their air-void systems, and absorption. Results showed that characteristsics of the air-void systems, relatively high compressive strength, and low permeability resulted in freeze-thaw resistance in a fresh water environment comparable to that of properly air-entrained concrete. However, for salt water exposure in a freeze-thaw environment, dry-mix shotcrete made with portland cement may require treatment with sealers or coatings or greater cover of shotcrete may be necessary to protect embedded steel reinforcement.
