The course aims to provide the elements for the recognition and classification of rocks intended as geomaterials (stone, lithoid, ornamental and derivatives) which, by their physical, chemical and technical properties, involved and affect human activity in the field of architecture; this knowledge is base for the recognition of geomaterials and their synthetic analogs, their use and their technical-application useful for defining characteristics, criteria, and use of ornamental and building stones. An essential goal of the course is to provide the knowledge of the physical, chemical and biological processes that lead to the deterioration of building materials and ornamental plants and also their regulatory issues. At the end of the course, the student will have the knowledge to recognize and describe the properties of the main natural stones (stones) and also of mortars, plasters, and the causes and mechanisms of deterioration of stone materials used. This knowledge is a prerequisite to define the characteristics, criteria, and use of ornamental and building stones.
Description and constitution of Geomaterials
Classification, properties and uses.
Knowledge of common minerals in the different types of rocks. General aspects about the classification criteria of the rocks. Igneous rocks, sedimentary rocks, metamorphic rocks. Petrographic and commercial classification of rocks. Regional districts natural stone . Outline of regional geology and the corresponding lithologies. Main rock types used in regional historical and modern stone monument and architecture. Petro-physical-mechanical properties. UNI NOR.Ma.L recommandation. Archaeometric aspects related to the study of the origin of stone materials of monuments in cultural and artistic context.
General aspects of degradation, causes and mechanisms of transformation of the rock and stone. The most important deterioration processes and their effects on the mineral-petrographic characteristics of different types of stones and rocks. Deterioration by physical, chemical and biological processes.
Determination of the chemical and mineralogical composition of raw materials and manufactured goods: the methods of taking of samples, X-ray diffraction, X-ray fluorescence spectrometry, electronic microscopy and microanalysis
40 hours of lecture
22.5 hours Practice in the laboratory
Recognition and classification of rocks and ornamental stones
Practice in the field
Macroscopic identification ornamental stone historical and contemporary regional architectureThe course will consist of lectures ( 32,5 hours) and practical sessions (30 hours). Students will study the methods of investigation of geomaterials and the recognition and classification of rocks in lab sessions and during field trips
Verification of learning
Oral examination; recognition of various types of stones and rocks used in construction and architecture
