Reinforced steel is one of the most important building materials in civil engineering and improving intelligence reinforcement can greatly promote intelligent development construction industry. This research addressed problems slow speed poor accuracy manually extracting rebar processing information, which leads to a low degree intelligence. Firstly, based on digital image technology, preproces...

Clad rebars of four different base materials (20MnSiV, 35# steel, 45# and 55# steel) were successfully produced by a vacuum hot rolling process. A metallographic optical microscope (OM), electron backscatter diffractometer (EBSD), probe micro-analyzer (EPMA), salt spray corrosion chamber used to investigate the clad contour, properties, composite interface microstructure all rebars. The results...

Mashhad Plain affects by a series of active faults in the northern margin of the Binalud and the southern margin of the Kopet-Dagh mountain ranges. The activity of these faults forms the morphology of the stepped bedrock of the Plain. In addition, the faults’ activities in the Quaternary period are the main effective parameters in thickness and texture of aquifer deposits in Mashhad Plain. In t...

As the frequency of earthquakes has increased in Korea recent years, designing earthquake-resistant facilities been increasingly emphasized. Structures constructed with rebars are vulnerable to shaking, which reduces their seismic performance and may result damage human life property. Because construction requires maintenance sub-constructions, such as by cutting or compensating for missing reb...
