The invention relates to a method for measuring the quality of porous material, for instance concrete, whereby a body produced of said material is brought into contact with water, and that subsequently the migration of said water into said porous material is determined after which the quality is ascertained from the information thus obtained. As a consequence of said features it is possible to determine precisely the migration of the water into said concrete in which, with the help with the thus obtained information, statements can be derived relating to the permeability of the concrete, after which the remaining life time of the concrete can be estimated, and that possible reinstating measures, like the new application of an outside coat, the application of a paint coat or the injecting with plastics. The invention also relates to an apparatus for performing such a method.

La présente invention concerne un procédé de mesure de la qualité de matériau poreux tel que le béton. Ce procédé consiste à mettre en contact avec de l'eau un corps produit dans le matériau considéré, et à évaluer la migration de l'eau dans le matériau poreux, à la suite de quoi on déduit la qualité à partir des informations ainsi obtenues. Avec de telles caractéristiques, il est possible de déterminer avec précision la migration d'eau dans le béton considéré, grâce aux informations ainsi recueillies, il est possible de déduire des considérations se rapportant à la perméabilité du béton, à la suite de quoi il est possible de donner la durée de vie restante du béton, de même qu'il est possible de mettre en oeuvre des travaux de protection, tels que de nouvelles mesures de réhabilitation et notamment une nouvelle application de peinture d'extérieur, l'application d'une couche de peinture ou l'injection de plastiques. L'invention concerne également un appareil permettant la mise en oeuvre d'un tel procédé.
