STUDY ON THE IMPORTANCE OF PHYSICOCHEMICAL CHARACTERISTICS FROM THE WALLS IN THE REHABILITATION WORKS OF HERITAGE BUILDINGS

摘要

It is well-known that the most frequent cause of the degradation of heritage buildings is related to the presence of water because all the traditional materials used, are more or less porous and constitute the support of water migration in the form of salt solutions. In order to establish the technological solution for control humidity, it is extremely important to know the causes that led to the degradation of the building, subsequently establishing the technological solution to be used to eradicate humidity from foundations and walls. Establishing the execution technology is closely related to the preliminary investigation, so physicochemical investigations play an extremely important role. The investigated objective is the Wing C of '1 Decembrie 1918' University of Alba Iulia. Several archaeological, architectural, historical, cultural interdisciplinary researches have been carried out on this building and on the degradation of the masonry. The paper highlights the importance of determining the physicochemical characteristics in order to establish the rehabilitation technology.
