英国交通运输道路研究所研制出混凝土建筑质量无损检测装置。使用时的将八只喇叭状天线按压在混凝土墙壁上,测定钢筋反射的信号,经过分析便可得知钢筋腐蚀情况。
The British Institute of Transport Roads has developed a non-destructive testing device for concrete building quality. When used, the eight trumpet antennas were pressed against the concrete wall to measure the signal reflected by the steel bars. After analysis, the situation of corrosion of the steel bars can be known.
