Deterioration Identification of Structural Concrete Ground on Residual Bearing Capacities

Found on data of accelerated life test, the relationship between outward disease of structural concrete and holistic deterioration of building was analysed. The results indicated that: outward diseases of structural concrete, such as abrasion, scour erosion, and peeling, carbonization etc, are not hypostatic breakage for holistic building, so could not be regarded as the key points of deterioration identification at building. Deterioration appraisement should be focused on detections of engineering indices relating to structural inbeing quality and analyses of multifarious remainder relating to bearing capacity. Only in this way, deterioration degree of structural concrete and efficacious repair indices could be factually incarnated. Ground on testing multifarious bearing capacities, deterioration identification of concrete buildings was founded, and remedy principles corresponding to inbeing deterioration indices were put forward.
