Microwave measurement and imaging for multiple corrosion cracks in planar metals

Materials & Design, 2020
Metal structures (such as buried pipelines, steel bridges) are subjected to long-term corrosion in the harsh environment, once the anticorrosion layer coated on the metals peeled off, corrosion cracks will occur and result in pipeline leaks, bridge ...

Microwave resonance detection method for hidden crack depth in rock and cementitious mortar [PDF]

Scientific Reports
Before the rock in engineering projects such as mining, tunnel excavation, steep road construction, and oil and gas extraction undergoes failure, macroscopic and microscopic cracks will appear. The management or utilization of these cracks is inseparable

The Classification and Mechanism of Microcrack Homogenization Research in Cement Concrete Based on X-ray CT

Buildings, 2022
Old cement pavement directly overlaid with an asphalt layer produces many reflection cracks. Using microcrack homogenization technology to treat old cement pavement can effectively reduce the occurrence of reflection cracks. Micro-crack homogenization is

Detection of cracks in cemented loess of ancient buildings using remote sensing

Frontiers in Materials, 2022
The bases of ancient Chinese buildings are prone to deformation, cracks, and other hidden problems due to their age and other reasons. Rainfall and water seepage produce great harm to the cracks of soil plinths. Based on a ground-penetrating radar method,
