Cyclic compression fatigue properties of concrete are studied with the ultrasonic fatigue testing method with cycling frequency 19 kHz and are compared to servo-hydraulic tests performed at 60 Hz. Ultrasonic testing was found applicable for rapid generation of very high cycle fatigue (VHCF) data of concrete. Fatigue cracks can be initiated, however specimens do not rupture, since cyclic stresses decrease with increase of compliance in displacement controlled ultrasonic tests. Observation of resonance frequency, analysis of higher order harmonics of vibration, and computed tomography of specimens are successful methods to analyse fatigue damage. Calorimetric evaluations can be used to calculate the cyclic irreversible strain, which is about 1% of the elastic strain in the ultrasonic VHCF test.

使用循环频率为 19 kHz 的超声波疲劳测试方法研究混凝土的循环压缩疲劳性能，并与在 60 Hz 下执行的伺服液压测试进行比较。发现超声波测试适用于快速生成混凝土的超高周疲劳 (VHCF) 数据。可以引发疲劳裂纹，但试样不会破裂，因为循环应力随着位移控制超声测试中柔量的增加而降低。共振频率的观察、振动的高次谐波分析和试样的计算机断层扫描是分析疲劳损伤的成功方法。量热评估可用于计算循环不可逆应变，其约为超声 VHCF 测试中弹性应变的 1%。
