Selective Optical Properties of Cement for Enhanced Radiative Cooling and Energy‐Efficient Construction Materials

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
Cement phases are good materials for radiative cooling thanks to the selective emissivity in IR ATW. Cement powders have high reflectance of solar radiation which reduces the thermal losses. The onset of the absorption curves is defined by bound excitons. Sulfates have higher radiated powers and reflectance than calcium silicates.
