Durability Evaluation of a Geothermal Grout
The durability of a geothermal grout used to seal vertical geothermal probe is evaluated. The study integrates an experimental approach and geochemical models simulations. The accelerated ageing of the geothermal grout is evaluated in laboratory subjecting the grout to realistic geochemical and thermal aggressions to which the grout can be subjected. The parameters related to the thermal conductivity and the permeability are particularly monitored. An experimental setting is developed to reproduce the operating conditions of a geothermic probe under realistic containment conditions. The experimental results are the input of the geochemical degradation models leading to the simulation of long time scale degradation around the probe. Conclusions relating to the service life rise from this study.
