The manufacture of CSA cements is more environmentally friendly than that of OPC as it releases less CO2. This reduction depends on CSA composition and is due to three factors: i) less emissions from decarbonation in the ...

Cement matrices contain large amounts of crystalline phases jointly with amorphous and/or nanocrystalline phases. Consequently, their analyses are very challenging. Synchrotron powder diffraction in combination with the ...

A cement powder, composed of belite, alite and ye’elimite, was blended with 0, 15 and 30 wt% of fly ash and the resulting lended cements were further characterized. During hydration, the presence of fly ash caused the ...
