Rehabilitation of historic structures using modern techniques:

When repairing and restoring historical buildings, the challenge is to preserve their value. It is essential to use materials that closely match the originals in both composition and application methods. This paper aims to synthesize current techniques and methods for selecting building materials in the rehabilitation of historical structures. A bibliographic study was conducted to examine the causes and types of degradation, the evolution of construction and building materials over time, and the current methods for analyzing their characteristics and compatibility with the original materials. The theoretical analysis revealed that historical buildings can degrade due to natural causes (chemical, physical, biological, and mechanical) or traumatic events (fires, earthquakes, and wars), leading to a reduction in structural strength and stability and a loss of historical value due to the deterioration of architectural details.Throughout history, construction methods and materials have continually evolved. Initially, less processed materials, closer to their natural state, were used. Today, complex composites are produced and utilized, offering multiple properties and benefits. However, in the repair and restoration of historical buildings, preserving their value presents a challenge.
