Using control flow concrete for tunnel linings. Concrete linings are a fundamental part of ensuring the structural integrity of tunnels, but pumping and placing the concrete for these jobs is a cumbersome process. For example: Access within the tunnel is very limited, so concrete with very good flow is critical. .
