REVIEW OF METHODS OF DESTRUCTIVE CONTROL OF THE CONDITION OF CONCRETE STRUCTURES AFTER A FIRE

It has been established that the assessment of the condition of concrete structures is an essential aspect of modern construction engineering, and the diagnosis of concrete structures at the site of a fire is necessary to make informed decisions about the possibility of conducting rescue and emergency recovery operations, organizing investigative actions and other measures. It is stated that in order to eliminate these limitations, a more common alternative strategy is to combine direct compression testing with advanced non-destructive testing methods, this approach allows for a more efficient and accurate assessment of the quality of the structural material without the need for extensive sampling and destructive testing. The main methods of non-destructive testing are analyzed: acoustic, optical, electromagnetic, thermal and radiographic. The task is to develop objective criteria for the selection of non–destructive testing methods for assessing the condition of concrete structures after a fire.
