Laboratory test method for irreversible thermal and hydrological properties

The developed test method will be the first method that provides a correct assessment of the potential risk of irreversible thermal and moisture expansion of carbonate rocks. Existing methods are not applicable for marble and limestone. The results will provide information for the assessment of durability in use environments where stone slabs will be exposed to temperature and/or moisture gradients. This is of special importance in exterior claddings, where insufficient joint widths and movement allowance at fixings may give serious damages in the stone cladding.

Decision makers, architects and building owners who select stone materials will need the test method and the results as a basis both for their material selection and construction design and also for the documentation of material behaviour and durability.

Producers of marble and limestone will have a major interest in having their stones tested according to the method developed.
