Monitoring and thermal characterisation of cement matrix materials using non-destructive testing

In view of the increasing worldwide demand for concrete, it is necessary to propose methods of testing associated with the building and follow-up of civil engineering structures. Concrete is a complex, multiple-phase material that is subject to atmospheric stresses. Its composition and implementation are very important for its life duration. The purpose is to propose different methods of non-destructive testing of cement matrix materials, based on heat transfer. The values obtained are linked to the state of maturity or alteration of the system in question.
