Hardening Mechanism Of Calcium Aluminate Cement
Feb 09, 2018

Calcium aluminate cement condensation and hardening speed is also related to the curing temperature, CA2 minerals with the curing temperature increased, condensation hardening speed, and CA minerals some abnormal, in 20 ℃ around faster, to 30 ℃ and slowly, more than 30 ℃ and faster. It is very important to choose suitable curing conditions according to the phase transition during the heating process of calcium aluminate hydrate, because the hydration of calcium aluminate cement varies with the curing conditions.


In actual use will often see a lot of different grades of calcium aluminate cement, marking is the cement curing a certain time after the strength reached, for example, Calcium aluminate cement with CA as its main mineral is usually labeled as the strength of 3d after its maintenance, while the calcium aluminate cement with CA2 as the main mineral is labeled as the strength of its 7d after its maintenance.
