Concrete mixture was mixed for 8 min in a laboratory RILEM-cem mixer. Afterwards, mixture was poured into moulds and cured for 24 h at room temperature (20 °C) in a controlled relativehumidity (φ

The salts found both on the surface and within the main body of the plaster
increases with increasing temperature. Relativehumidity is the ratio in percentage between the absolute humidity and humidity at saturation:
At saturation, p = P, and the relativehumidity is 100%. For example, a pure cotton paper in a

and ambient relativehumidity during the day or year or season are also reflected in large variations in skin admittance, mainly because of changes in skin hydration [ 5 ].
In recent years, there is a growing interest in employing the
