Abstract:
Concrete berth faces at the Port of Montreal, Quebec, Canada, constructed in the early 1900s have deteriorated from the combined effects of frost action, salt attack, and alkali aggregate reactivity. This article describes remedial work that was conducted using wet-mix, fiber reinforced, air-entrained, silica fume shotcrete. Part of the wharf was repaired using high-volume additions (1.25 percent volume) of a synthetic monofilament polyolefin fiber. The remainder of the wharf was repaired using conventional addition rates of steel fiber reinforcement (0.75 percent volume).
