Influence of climatic conditions on the carbonation of quicklime
The influence of relative air moisture, temperature, and concentration of carbon dioxide (CO2) on the carbonation of quicklime (CaO) have been studied in normal climatic conditions. The CaO used for this original work is a granular material prepared by calcination of pure calcium carbonate (CaCO3). The influence of time and mechanical treatment has been studied, too, to obtain a complete carbonation. A model of hydration and carbonation has been established to explain the observed phenomena. The work was carried out with the view to defining the optimum conditions for the storage of CaO. The process is usually carried out in storage silos at relative humidities approaching 30 % and temperatures not rising above 40 degrees C within the mass, where atmospheric conditions are assumed to be low in CO2. The time period involved is no longer than 10 days. The results of this study show that the risk of carbonation is low. The conditions usually adhered to in the manufacturing industry guarantee the high quality of the goods being delivered.
