Concrete Structure Ultrasonic Testing Technology Research Latest Progress and Development Trend

Abstract

Many concrete structures in use have safety problems due to material deterioration, actual construction defects, structural damage, etc. Therefore, nondestructive testing is required to determine the presence of defects. Ultrasonic technology is an important tool in nondestructive testing, which can detect defects in concrete and be combined with other methods or models to make it more accurate. At present, ultrasonic inspection technology has been more research at home and abroad, both in theory and in engineering, and there has been great progress. This paper summarizes the latest progress of ultrasonic inspection technology for concrete structures at home and abroad respectively, and points out the future development trend.

Comparative analysis of ultrasonic testing and ground penetrating radar (GPR) for concrete structure evaluation

“…When detecting corrosion and cracking in concrete structures, ultrasonic testing has high-resolution imaging, which can draw detailed corrosion patterns and accurately identify cracks and other defects in concrete [5]. However, ground penetrating radar may face limitations in detecting small cracks or corrosion in reinforced concrete structures, as radar signals may attenuate or scatter.…”
