marble Fior di Pesco Carnico
bowing - Opis:
- Due to its exceptional ornamental properties, the marble Fior di Pesco Carnico (FDP marble) is a common decorative stone applied to external and internal building elevations. The rock is characterized by a considerable structural and textural variability; however, this feature pertains only to a minor degree to its directional arrangement of anisotropy planes (i.e. lamination) being usually dependent on the non-uniform, spatial distribution of rock mineral components or some textural elements, mainly veins. As a result, the utilitarian properties of the FDP marble varies dependingon therockzone. Petrographic AGA(Adjacent Grain Analysis) investigations were carried out on samples representing various fragments of a marble slab and essential mechanical parameters of the rock were determined. It has been established thatthe FDP marble is deformable asaresultof temperature changes (bowing) and that this feature can be explained to asignificant degree by the type ofcontacts between calcite blasts (AGA = 6). Other highly variable marble properties include the flexural strength under the concentrated load and the breaking load at dowel hole in different places of a marble plate. It has also been shown that applying to computational project works lower values of the expected mechanical rock parameters instead of their mean values has a ensible justification, as to a large extent it secures a higher exploitation safety of the marble to be used within a building object.
