Comparative kinetics study on carbonation of ettringite and meta-ettringite based materials
Cement and Concrete Research, 2020 Abstract The use of ettringite-based materials for thermochemical heat energy storage has attracted researchers' attention in recent years since ettringite has advantages like low material cost and high energy storage density (~500 kWh/m3). However, carbonation, which modifies its structure and reduces the capacity of energy storage, is an important ...
