摘要

Detection and identification the damage of concrete structures is the most important tasks guaranteed the reliability of repair project after fire. Detection the damage depth is important to comprehensive assess the damaged of concrete structure after fire. The ultrasonic detection method at single surface is introduced. It is a significant task to develop a special instrument for concrete damage depth test after fire. A kind of ultrasonic detection instrument is developed by using high precision timing circuit, sensor driving circuit and automated gain circuit. The precision and anti-interference character has been enhanced in the instrument. The damage depth detection method and the instrument presented in this paper are testified fine practicability by experiment.
