Effects of carbonation temperature and compacting pressure on basic properties of calcite block were studied using Ca(OH)2 compact made with 0.2-2.0 MPa and their carbonation at 200-800ºC for 1 h. Microporous calcite was obtained only when carbonated at 600ºC using Ca(OH)2 compact made with 0.2 MPa even though thermogravimetry analysis showed that calcite powder was stable up to 920ºC under CO2...

The study area is located in the state of Minas Gerais, Brazil, among the municipalities of Pedro Leopoldo, Matozinhos, and Sete Lagoas, with Velhas River as the eastern boundary. It is located in the São Francisco Craton, where carbonated argillo-arenaceous sediments are emplaced giving origin to the Bambuí Group, in the São Francisco Basin. Despite the geological knowledge previously develope...

Carbonated produced water injection (CPWI) might be considered an efficient alternative to handle the largest waste stream while enhancing oil recovery and storing carbon dioxide (CO2) underground. This study was attempt get a deeper understanding of process through synergy between spontaneous imbibition isothermal titration calorimetry (ITC) experiments. The results from experiments showed 7% ...

This paper aims at discussing an automated measurement system for detecting carbonation depth in concrete sprayed with phenolphthalein. Image processing and Convolutional Neural Networks strategies are exploited to accurately separate the carbonated non-carbonated areas remove those aggregates on front that could bring a wrong evaluation of depth. Very strong correlation (R2 = 0.96) is found be...
