Importance of Physico-Chemical Methods in Evaluating the State of Building Structures and Design of their Redevelopment

Article Preview

Abstract:

The experience in building practice proves that in assessing and evaluating the state of reinforced concrete structures, also professional companies place a clear emphasis mainly on determining the strength characteristics of concrete, assessing the rate of corrosion and the distribution of reinforcements in assessed elements. Obtaining these data is essential for the structural analysis of a structure. However, from the view of a complex evaluation of the state of structures, this information is quite insufficient, for example because of fully omitting the evaluation of the state or rate of degradation of concrete by action of chemically aggressive substances from the outside environment. For example, it is not possible to predict further life of a structure in a relevant manner on the basis of facts only found out by testing the strength characteristics of concrete.
