【 摘 要 】

This paper studies the variation of the dynamic elastic moduli and R-wave velocities of epoxy mortars with different binder to sand ratios subjected to a wide range of temperature change. It is found that, unlike concrete, the dynamic elastic moduli and R-wave velocities of epoxy mortars all decrease with increasing temperature, and a clear "knee" at around 30 °C divides the curves into two approximately linear parts. Therefore, to guarantee a correct interpretation of the in-situ SASW results, the temperature-dependent R-wave velocities of epoxy mortars must be fully understood beforehand.
