CRACKING OF CONCRETE IN THE PROCESS OF OPERATION OF STRUCTURES

B. H. Klochko, O. O. Kushvid

Abstract


The article presents the results of experimental and theoretical studies of the conditions of concrete destruction in the structures, exposed to the influence of aggressive media. The possible mechanisms of micro-crack formation, depending on the structure of the concrete, have been described.


Keywords


concrete; aggressive media; micro-crack formation
