Meeting shotcrete specifications
23 March, 2010
In the long history of shotcrete, or sprayed concrete, linings underground, never has so much been expected of them. In the transition in scope from hard rock primary support to soft ground permanent support, shotcrete is now expected to create structures under even more demanding conditions, but still at comparatively low cost. Here technical editor Maurice Jones reviews the state of some developments designed to meet such demands
