Cement - Wikipedia

A less common form of cement is non-hydraulic cement, such as slaked lime (calcium oxide mixed with water), hardens by carbonation in contact with carbon dioxide, which is present in the air (~ 412 vol. ppm ≃ 0.04 vol. %).First calcium oxide (lime) is produced from calcium carbonate (limestone or chalk) by calcination at temperatures above 825 C (1,517 F) for about 10 hours at atmospheric

Calcium aluminate cements are also used in coination with other fine components. Hydraulic binders with new properties are then obtained. In this way, aluminates act as both a complex hydraulic binder and a mineral reagent interacting with the other components in the mix.

Calcium aluminate cement conversion analysed by …

Abstract Calcium aluminate cements are used for special appliions but are nowadays banned for general structural purposes due to the calcium aluminate hydrate conversion, that has led, for concretes fabried with high water contents, to building collapses. The stoichiometries of these conversion chemical reactions are relatively well established but the consequences in porosity, key to
