Abstract

Knowledge of the humidity transport inside materials and building construction elements present a high role in the characterization of their behavior in service. It is a vary complex phenomena, where monolithic elements are considered since the existence of interface or layers contributes to the change of the moisture transport across the interface. This work presents an experimental analysis of the moisture transport considering the interface ceramic bricks. This preliminary experimental work consists of quantifying, analyzing and deepening the knowledge of hydric resistance in the interface of "contact" through ceramic brick test samples with different densities. In addition, this work also comprises an attempt to create a prediction model for the hydric resistance. The results describe the influence of hydric resistance in the interface as a function of the distance from the interface to the water plane.
