Part of the special publication: SP-407 (2015). Global Heritage Stone: Towards International Recognition of Building and Ornamental Stones (Edited by D. Pereira, B. R. Marker, S. Kramar, B. J. Cooper and B. E. Schouenborg). 978-1-86239-685-2Colmenar Limestone is one of the traditional materials most commonly used in\udmonuments in Madrid, Spain. The petrophysical properties of this stone determine its\udhigh resistance to decay. Its low water absorption and pore size distribution favour\udgood hydraulic behaviour, which is likewise furthered by its high ultrasound velocity and\udlow anisotropy. The durability findings pursuant to the 280 freeze-thaw, 42 thermal\udshock, 30 salt crystallisation and 120 salt mist cycles conducted confirmed the stone’s\udresistance to decay in these simulated aggressive environments. The mass loss\udrecorded in the samples and the variation in petrophysical parameters were generally\udvery low after all except the salt crystallisation trials, which induced loss of cohesion on\udthe stone surface, increased roughness and the formation of concentric microcracks,\udsub-parallel to the more exposed surface, that also affected the arris and vertices of the\udspecimens tested.This research was funded by the Geomaterials (S2009/MAT_1629) and\udCONSOLIDER-TCP (CSD2007-0058) research programmes, and by the Complutense\udUniversity of Madrid’s research group on the Alteration and conservation of heritage\udstone (921349).Peer reviewe
