Research on the application of ultrasonic pulse velocity method in fire-damaged concrete

Abstract

The number of fires that break out in buildings accounts for most of all fires worldwide. People are very concerned about the damage to the concrete structure after the fire because the safety of the fire-damaged concrete structure needs to be assessed. The Ultrasonic Pulse Velocity Method is most frequently employed in the non-destructive evaluation of fire-damaged concrete. The UPV method has been widely used in the concrete industry for over fifty years. It is an essential non-destructive technique because it uses relatively inexpensive equipment and can provide reliable results quickly. This paper summarizes the traditional methods of using UPV in fire-damaged concrete, the application of UPV in new fireproof materials, and the use of UPV on other potential test objects. Whats more, this paper also provides suggestions for the future development of UPV testing, so as to improve the repair and evaluation efficiency of fire-damaged concrete structures.
