Huge opportunities for industry of nanofibrous concrete technology
In spite of the fact that cementitious and concrete materials are mainly used on a large scale and in huge quantities for roads, dams, bridges and building constructions, the mechanical behavior of these materials depends to a great extend on structural elements and phenomena which are effective on a micro and nanoscale. Although this is well known by researchers, material producers and enginee...
متن کاملNovel sensor technology for NDE of concrete
This paper describes the application of a novel actuator/sensor technology for the generation and detection of stress waves in structural materials like concrete. The technology is aimed at developing an innovative NDE scheme based on the generation of highly nonlinear solitary waves (HNSWs). HNSWs are stress waves that can form and travel in highly nonlinear systems (i.e. granular, layered, fi...

متن کامل3D Microwave Imaging Technology For Damage Detection of Concrete Structures
Various nondestructive evaluation (NDE) techniques have been studied to locate steel rebars or dowel, and to detect invisible damage such as voids and cracks inside concrete and debonding between rebars and concrete caused by corrosions and earthquakes. In this study, the authors developed 3-dimensional (3D) electromagnetic (EM) imaging technology to detect such damage and to identify exact loc...
