Abstract: To clarify the effect of environment temperature on the ultrasonic wave testing, the ultrasonic velocity in ordinary Portland cement concrete (OPC) and high performance concrete (HPC) were researched under temperature of -10°C up to 30°C. Results showed that the effect of temperature on ultrasonic velocity could not neglected in OPC, especially at low temperature. The influence of temperature on ultrasonic wave velocity to the size effect of samples could be ignored. The variation of ultrasonic wave velocity with temperature in C30 concrete is consistent to C40 and C50 concrete. On base of this, the temperature correction coefficient of ultrasonic wave velocity in concrete was deduced. On the contrary, the environment temperature had slight effect on the ultrasonic wave velocity in HPC.
