The actual requirements in the practice of renovation and reconstruction need detailed analysis for the exact theory concerning the general causes and effects on the materials of construction. In addition, these causes need to be categorized and treated individually in order to be available in the literature of the theory: Pathology of materials. This work is to analyze and classify the failure caused by many recognized effects upon buildings constructed from reinforced concrete or masonry bearings systems that attribute to the mentioned scientific line in the area of renovation and reconstruction. The objects of the categorizing and analysis are the following causes: (1) interior forces; (2) exterior forces. The result of research, testing, and the new theoretical information shows a significant process in the knowledge of serviceability, durability, strength and the age of construction materials especially the concrete. Obtaining the correct information about the concrete, as material required destructive and nondestructive testing, these help in getting results to assist in the analysis of concrete failures for putting up an adequate solution for its repairs. Results obtained from the theoretical study and laboratory testing reveled significant information on concrete failures.

Failures, damaged structure, destructive and nondestructive testing, seismic wave reflection, freeze thaw cycles, alkali, silica reactivity, durability, and serviceability, pathology of materials, repairs and restoration.
