Abstract:
Defects in concrete tunnel linings such as disinte-gration, honeycomb cracking and structural Failures and faultv conditions in earth and rock formations through which tunnels have been bored have been corrected with treated mortars, a special concrete and through unconventional methods of ap-plying them.
