Human activity has required, since its origins, stones as raw material for carving,
construction and rock art. The study, exploration, use and maintenance of building stones is …

Microcracking induced by wide fluctuations in temperature affects granite quality and
durability, making the stone more vulnerable to decay. Determining the extent of that effect is …

Fire is one of the most severe threats to stone applied in civil engineering and architecture.
In most cases, its effects are irreversible and have long-lasting repercussions. In addition to …

Four types of granite widely exported and used in construction around the world were
subjected to 280 accelerated freeze–thaw test cycles, conducted as stipulated in European …

It is important to have a thorough knowledge of the petrographic characteristics of rocks to
evaluate and understand their mechanical behavior. This paper deals with the influence of …

To provide guidance for using Schmidt hammer rebound number (N-type hammer: RN) to
predict uniaxial compressive strength (UCS) of heterogeneous building stones, this paper …

The thermal rock properties are particularly important for natural stones whenever a
temperature change may occur, which becomes particularly important when different …

From a consideration of the concepts of geological weathering and structure, it can be
expected that rockfall hazards should be characteristically different in different geological …

Volcanic tuffs are notoriously very heterogeneous materials exhibiting a recurrent
lithological diversity, which, in turn, can be associated with changing petrophysical and …

The use of a rock as a building stone is conditioned by several factors, from its aesthetic
characteristics to its petrophysical properties. Even though the latter are taken into …
