dc.description.abstractThis thesis deals with deterioration mechanisms affecting steel fibre reinforced sprayed concrete used for rock support in tunnels. Physical and chemical degradation of sprayed concrete linings may contribute to destabilisation of the rock mass, involving increased maintenance costs, reduced service life, and a potential safety risk. The principal aims of this work were to a) provide an updated and modern diagnosis of chemical degradation phenomena occurring in steel fibre reinforced concrete used for rock support, b) investigate the reaction mechanisms involved including the possible interaction of different reaction schemes, c) characterise the environmental loads, mainly with respect to water chemistry, microbial activity and hydrogeology, and d) attempt to establish links between scientific findings and practical engineering issues, such as durability and life time aspects, maintenance/repair and consequences for rules and recommendations.nb_NO
