Abstract:
Defines wet-mix shotcrete and describes both positive feed and pneumatic feed equipment for delivering the mix. Gunning techniques and the solution of rebound problems are also discussed. Preconstruction mock-ups helped solve production problems in wet-mix shotcreting of a large folded plate roof for a church, indicating a need to combine cast concrete with shotcrete. Successful bonding at the construction joints is described. Comparative data on cost and properties of wet-mix shotcrete and cast concrete are given.
