Many studies have shown that artificial neural networks (ANNs) are useful for predicting the
unconfined compressive strength (UCS) of rocks. However, ANNs do have some …

Two types of Hungarian travertine a massive less porous and a laminated porous type were
tested under laboratory conditions. Tests aimed to assess the performance and durability of …

Weathering processes cause important changes in rock porosity. Besides porosity,
distribution of pore sizes is significant for the identification of changes due to rock …

Although, many studies have been carried out to determine physical, dynamic and
mechanical properties and to establish relationships among them for several rocks, only few …

A large number of laboratory tests were performed on intact chemical and clastic
sedimentary rocks (marlstones, sandstones and limestones). Index properties such as total …

Natural and anthropogenic caves may represent a potential hazard for the built environment,
due to the occurrence of instability within caves, that may propagate upward and eventually …

The application of non-contact diagnostic methodologies is the current challenge in the
frame of the cultural heritage, referred to as preservation, monitoring and restoration …

Rocks are natural geo-materials, whose properties are affected by many spatially-varying
factors, such as the properties of their parent materials, weathering processes, and …

Limestones are of wide variety, namely with differences in the process of formation,
mineralogical composition, grain size and texture. Such variability leads to differences in …

The statistical analysis of the main physical, mechanical and ultrasonic features of various
sedimentary rock samples (limestone, calcarenite, marly calcisiltite and sandstone) is …
