SUAREZ-BURGOA, Ludger O. Assesment of the Mechanical Variability of Rock Slabs by Means of Non-Destructive Tests. ing.cienc. [online]. 2014, vol.10, n.19, pp.221-246. ISSN 1794-9165.

In this article it is described a systematic test campaign -with the Schmidt- L-type rebound hammer- that was performed at a Sodalite slab of 0.05m thick in a square area of 2.0m of side. This research revealed that the studied ornamental rock has an inherent variability by it-self, in respect to their mechanical strength; and also a spatial variability related to their position, this last with a clear sign of a preferential direction. These variabilities can be detected with the proposed test-campaign and the use of geostatistics; whose conclusions are useful for the the quality control of rock-material-slabs used for ornamental purposes.

Palabras clave : rock material; Sodalite; Schmidt-L hammer; mechanical strength; spatial variability.
