Bonding Calcium Chloride and Calcium Nitrate into Stable Hydration Portland Cement Products: Stability Conditions of Calcium Hydrochloraluminates and Calcium Hydronitroaluminates

Abstract:

A thermodynamic analysis of the reactions of calcium chloride and calcium nitrate with tricalcium aluminate when used as a hardening accelerator for portland cement, as well as decomposition reactions of calcium hydrochloraluminate (CHChA) and calcium hydronitroalyuminate (CHNA) formed during the hardening was performed. The conditions of stable existence of CHChA and CHNA in the cement matrix were established.
