Abstract

In order to study the internal damage and static compressive strength of concrete under different water pressures, the wave velocity test and compressive test were carried out by NN-4B non-metallic ultrasonic testing analyzer and electro-hydraulic servo testing machine. The test results show that the high water pressure of concrete has an adverse impact on the development of its internal structure, and with the increase of high water pressure level, the slower the longitudinal wave passes through the specimen, the more serious the damage and deterioration of concrete, and the compressive strength decreases gradually with the increase of water pressure.
