ABSTRACT
Typical results obtained on a specimen without cracks are shown in Figure 1. The obtained images obtained have been further evaluated by means of existing software IDL. In this way water profiles after certain durations of contact between the surface of the mortar specimens and water have been obtained. Typical results are shown in Figure 2. For the determination of the profiles the rectangular area marked in Fig. 1 has been selected. Moisture profiles move deep into the porous material in a comparatively short time. In practice dissolved ions are transported with the water into the pore space. The penetration depth of ions which is reached by convection during capillary absorption after a few hours would take several years if the transport were based on diffusion.
