Detection of the Reinforcement Corrosion in Prestressed Concrete Girders

Popis výsledku v původním jazyce

Prestressed reinforcement is a basic element of the structural stability in a great amount of concrete structures. The corrosion of reinforcement is a major cause of a failure of such structures. Therefore it is very important to find relatively inexpensive and adequately reliable non-destructive method that would be capable to determine prestressed reinforcement conditions. The paper deals with the usage of the acoustic emission method to testing of prestressed concrete girders from corrosive damage point of view. The experimental test investigated acoustic emission method to evaluation of deterioration of prestressed reinforced concrete girders during flexural tests under loadings. The girders were deteriorated due to accelerated corrosion of prestressed reinforcement. The tests demonstrated that acoustic emission is very sensitive to detect the initiation of tensile microcracks, main tensile cracks and internal cracks generated near the interface between the prestressed reinforcemen
