Abstract

In the present investigation building stones from the archaeological sites of Knossos, Festos and Malia in Creta are studied with regard to their weathering condition and to some of their physical and mechanical properties. For this purpose studies were made of: a) the mineralogy with a semi-quantitative composition of the materials by microscopic and X ray diffraction methods, and in situ observations b) the weathering condition either under the microscope or with ultra-sonic velocity measurements c) weathering resistance by salt crystallisation methods d) dry density and water absorption and e) unaxial compressive strength. All test results were interpreted statistically and the relationships were expressed mathematically: correlation diagrams are also given.

Durabilité des roches de construction et alteration des monuments anciens en crète/grèce

Résumé

En Crète, les monuments anciens de Knossos, Festos et Malia ont été étudiés pour identifier l'altération et les propriétés physiques et mécaniques des roches de construction. Dans ce but nous avons étudié: a) la minéralogie et la composition semi-quantitative des matériaux aux RX aussi bien qu'au microscope, b) l'état d'altération, calculé par les ultra-sons, c) la résistance à l'altération par attaque à Na2SO4 hydraté, d) la densité sèche et l'absorption d'eau et e) la résistance à la compression uniaxiale. Tous les résultats ont été étudiés par interprétation statistique les relations exprimées mathématiquement, des diagrammes de corrélation étant également établis.
