Abstract: (93 Views)
The stones are widely used as facades, flooring, paving, stair, kerb and load-bearing components in buildings. Weathering processes lead to adverse effects on stones from various aspects, including aesthetic (color) and technical properties. Any changes in aesthetic and technical properties will lead to the deterioration of the stone, resulting financial damages to the building from both architectural and structural perspectives. Understanding the mechanism of weathering processes causes stone deterioration can be as a useful and efficient tool in assessing the long-term durability behavior of stone during its service life in a building. In the present study, the mechanisms of the freezing-thawing and salt crystallization processes in the deterioration of building stones were systematically investigated. For this purpose, published papers regarding the deterioration of building stones, including igneous, sedimentary, and metamorphic, due to freezing-thawing and salt crystallization processes were collected. Discussions performed on the mechanisms of freezing-thawing and salt crystallization reported in these papers from different perspectives were compared. The findings indicate that in each of these processes, more than one mechanism involved in the deterioration of building stone. In addition, findings showed that depending on factors related to the surrounding environment of the stone and on the other hand the inherent properties of the stone, various mechanisms will have different adverse effects in the deterioration of building stone.
