SHOTCRETE: WET PROCESS VERSUS DRY PROCESS

shotcrete processes, dry-mix shotcrete (also known as gunite) and wet-mix shotcrete, have grown steadily in popularity in both concrete repair and new construction. This article will compare and contrast the two shotcrete processes. Dry-mix shotcrete is defined by ACI 506R as “shotcrete in which most of the mixing water is added at the nozzle.”

THE USE OF SHOTCRETE AS A REPAIR PROCESS FOR

Testing has indicated that in a concrete repair application, the shotcrete process often achieves a stronger and more durable bond than other place-ment methods.5 This is due to the principles of the shotcrete process and lead back to the previous statement referencing the importance of velocity.
