| Abstract |
This work studies the suitability of the Torrent air-permeability test method for testing dimension stones. To test its feasibility, measurements were performed on stone slabs with porosities in the range of 0.2-17.2 \%. Statistically, accurate and reliable measurements were achieved on stones with open porosities above 2 \%. Close relations were found between air-permeability coefficient and other transport-related properties. Therefore, the air-permeability coefficient can be a parameter, on its own, providing useful information about the stone susceptibility to decay. Moreover, a graded classification is suggested with the purpose of providing information for a proper application of stones in constructions. |
