Abstract
One of the most effective methodologies for the evaluation of the penetration of water into the bulk of stone materials is the capillary absorption measurement. In this paper the Authors would like to propose a short theoretical presentation of the two new parameters - the ICa (Absolute Capillary Index) and the ICr (Relative Capillary Index) - for capillary measurements recommended in the Italian Protocol Norma UNI 10859 Cultural Heritage Natural and artificial stones Determination of water absorption by capillarity.
