Effects of Shock Vibration on Concrete
|
The effects of shock vibration on concrete were studied using a newly developed test method that applies hammer blows to prismatic specimens in the longitudinal direction and evaluates the shortand long-term effects by observing crack formation, measuring the immediate change in ultrasonic pulse velocity, and measuring the reductions in 28-day tensile and compressive strengths. A total of 198 prisms cast of typical concrete mixtures with 28-day cube strength ranging from 40 to 60 MPa had been...
