Natural Carbonation of Thermally Damaged Cement Mortar Studied by Thermogravimetric Analysis
Year: 2014
Type: article
Abstract: The objective of this study was to examine the natural carbonation that occurs during the cooling of thermally damaged cement mortar. Thermogravimetric analysis was used to follow mineralogical changes of CEM II mortar which was treated at different temperatures from 105 to 500°C. The results showed that, during the cooling to ambient temperature, by capturing CO2 from atmosphere the cement mortar tends to gain calcium carbonate from the loss of portlandite which was caused by heat treatment. This natural carbonation process allows the thermally damaged mortar to autonomously generate self-healing effect so that it can regain the initial properties.
