gypsum formulations have to be hydrophobized in order to achieve sufficient water resistance. Cured gypsum mortar consists of 50-60 vol% pores, most of them having a pore size between 0.3 – 1.0 µm. This means that pores in a gypsum matrix have diameters, where capillary suction forces are active (Jakobsmeier, 2000). The high content of these

The contact angle is the angle, conventionally measured through the liquid, where a liquid–vapor interface meets a solid surface. It quantifies the wettability of a solid surface by a liquid via the Young equation. A given system of solid, liquid, and vapor at a given temperature and pressure has a unique equilibrium contact angle. However, in practice a dynamic phenomenon of contact angle hysteresis is .

In the case of hydrophobized materials this characterization may not only be useful for description of porous structure but also for measurements of hydrophobization degree of such solids. The obtained results allow for assessing the direction of changes of limestone powder's properties caused by the hydrophobization process.
