Material and structural destruction of concrete elements in the industrial environment

摘要

A brief review of selected models which are currently used to describe the service life of structural systems, especially made of concrete is presented, taking into account influences and processes that cause material destruction and decrease in structural durability of such elements. There are also mentioned the models, verified experimentally in laboratories on simple samples, that can lead to define remaining (residual) service life of deteriorated RC structures. This is of great importance for proper planning and execution of repair works for degraded structural elements to maintain their further functionality. Finally, some examples of real assessment of condition, causes of deterioration and methods of repair of concrete structural elements deteriorated by the influence of industrial environment aggressive agents are presented.
