Hydration of calcium aluminate cement determined by thermal analysis

Popis výsledku v původním jazyce

Calcium aluminate cements (CACs) are a very important type of non-Portland or special cements. Since they are considerably more expensive, they are not used as a simple substitute for Portland cement. Their structure allows them to achieve high compressive strength. They resist very well to high temperatures and temperature changes, or also to chemical attacks. The original motivation, why the CACs were developed, was the idea of finding new cement chemistries that would be more resistant to sulfate attack then Portland cements. Nowadays, the main usage of the CACs is in high temperatures applications. In this paper, we study the hydration of a CAC up to one year of age to control what happens in CACs structure during aging. The variety in the main products of hydration is studied using differential scanning calorimetry and thermogravimetry in the temperature range from 25 °C to 1000 °C with a heating rate of 5 °C/min in an argon atmosphere. The basic physical and mechanical properties are also determined.
