Sprayed Concrete: Tunnel Support Requirements and the Dry Mix Process
The particular structural requirements of sprayed concrete acting as an arch or a ring to support a Carboniferous shale in the Kielder Water Scheme experimental tunnel are described in the light of detailed performance studies of several support systems over a period of two years. The rate at which the concrete stiffens needs to be optimized for economy and safety in relation to the timing and position of constructional operations and their influence on the dilation of the rock, particularly in small tunnels. The inherent characteristics of the dry-mix spraying process, all of which effect the quality of the concrete, are presented from the results of laboratory and field trials.
