Abstract

Cement hydration continues to have an intriguing character, surrounded as it is by a number of intensively debated questions. Among the unresolved issues is the reason why hydration stops at a relative humidity of about 80%, even though the system still contains a fair amount of water. This short communication shows that a critical relative humidity, below which hydration should stop, can be defined from a relatively simple thermodynamic treatment.
