超声波声时判断混凝土的密实性与均匀性

Ultrasonic Sound Judgment on the Concrete Compactness and Uniformity

超声波波速及均方差与混凝土的密实性及均匀性有一定的对应关系,根据被测物不同的测试面选择不同的换能器布置方法,通过超声波波速及均方差的数值计算分析,进而判断混凝土的密实性及均匀性。

As there is correspondence between w^locity and mean square error of ultrasonic sound and concrete compactness and uniformity, we choose different arrangement of transducer for different analyte test. We analyze and compute the values of ultrasonic wave velocity and mean square error to determine the density and uniformity of concrete.
