Interests: environmental geochemistry and mineralogy; natural stone durability; petrographic features and stone decay; salt weathering; porous media; weathering processes in the built environment; effects of pollutants on stone decay; stone decay as markers of pollution effects; conservation strategies for stone architectural heritage
The main goal of this special issue will be the relevance of the geosciences for the study of the built environment, assessing the problem-situation especially on the following issues:
- Selection of Building Materials
Selection of materials (masonry and carved stone; aggregates for mortars, concrete and bituminous pavements; raw materials for the manufacture of other building materials such as cement, bricks, tiles and glass) needs to consider aesthetic features and the characteristics that influence the performance of the materials in the built environment regarding durability, energy efficiency and pollution effects (also in a perspective of sustainability).
- Weathering Processes
The same weathering processes that act on rock outcrops affect the built environment surfaces. There are specificities related to the kind and contents of pollutants related to anthropogenic activities and with the geometrical configurations of the built elements (namely in relation to the circulation of polluting solutions and in the exposition to the climatic conditions), resulting in weathering products involving neoformation of substances or the cracking and erosion of the existing surface. The study of these processes requires observational studies (including mapping of weathering products) and in situ and field characterization of the weathering products (namely by non destructive techniques).
- Study Methods
Includes theoretical models applied to explain (and foresee) the evolution of the materials and the relation between the influencing factors, including numerical simulation and procedures for simulation in the laboratory or in the field in relation to the simulation conditions and the morphology and size of the specimen and confrontation of results of these experimental studies and the features observed in the field.
- Environmental Impact
Release of pollutants (including radon) from materials applied in the built environment and as waste and their impact on organisms and other materials, as well as the impact of the built surfaces on the energy budget of the surrounding environment.
- Pollution Monitoring
Geologic materials used as passive monitors of organic and inorganic pollutants and in retrospective dosimetry of radiation.
- Historical Research
Including historical uses of geological materials and its relation with the economic and technological development and also dating of built elements.
Relevance of the understanding of the interactions between weathering processes and the geologic materials for the conservation of the cultural heritage.
