含水率对受损混凝土超声波波速的影响

The Effect of Water Content on the Damage Concrete Ultrasonic Detection

为了揭示含水率对受损混凝土的超声波波速的影响规律,研究了不同损伤程度的混凝土试块在不同含水率下的超声波波速。研究结果表明,含水率<1.5%时,含水率对混凝土超声波波速的影响较小,可以忽略;含水率>1.5%时,超声波波速随含水率的提高而明显增大;损伤越大,这种影响就越明显。

The ultrasonic velocity was detected in order to research the relation between the ultrasonic velocity of the damage concrete and the water content, the result showed that the effect was little when the water content below 1.5 % ; and the effect increased obviously with the increment of water content when the water content was above 1. 5 %, and the effect increased when the damage level increased.
