Methods for the analysis of materials used in the rehabilitation of historical constructions

Abstract

In the case of repairs and restoration of historical buildings, the difficulty lies in preserving their value. It is important that the used materials to be as similar as the original ones, both in terms of composition and of application mode. The purpose of this paper is to present a synthesis of current analysis of techniques and methods for the used building materials in the historical buildings rehabilitation. Therefore, a bibliographic study has been carried out regarding the causes and types of degradation, the evolution in time of construction and building materials and the current analysis methods on their characteristics and the compatibility with the original substrate, too. The results of the theoretical analysis have shown that the degradation of historical constructions can occur as a result of natural causes (chemical, physical, biological and mechanical) or traumatic (fires, earthquakes and wars), resulting in strength and stability reduction of the structure, the loss of historical value due to deterioration of the architectural details etc.
