摘要：

Electrical resistance can be a relevant indicator for the assessment of water transfer in porous materials. The aim of this work was to establish a relationship between electrical resistance and water saturation in the case of two limestones used as building stones in the Chateau de Chambord in France: tuffeau and Richemont stone. For this purpose, firstly the electrical resistance matching different values of degree of saturation was investigated. Experimental measurements were performed to determine a relationship between the electrical resistance and the degree of water saturation, with high sensitivity. Secondly, using this relationship, the capillary imbibition curves and imbibition coefficients of the two stones were precisely determined by electrical resistance measurement. (C) 2018 Elsevier Ltd.
