Description
The pore structure of the backfill and liner may be affected by the degradation of cement, by damage due rock movements, by volume expansion due to corrosion of reinforcements and rock bolts, or become clogged due to microbial activity and the precipitation of cementitious components and calcite. Such effects are neglected, as they would have a small impact on mass transport.
