摘要
在混凝土强度超声检测过程中 ,分析了含水率对混凝土中超声声速的影响程度 ,建立了混凝土水饱和状态和绝干状态超声声速与自然干燥状态声速的换算公式 。
During the strength test of concrete by ultrasonic technique, the considerable effect of water content on the ultrasonic velocity in concrete was analyzed. Two conversion formulae for ultrasonic velocities in water saturated and absolutely dry situations against naturally dry situation were presented respectively. Suggestion was also proposed that the water content term should be taken into account in ultrasonic concrete strength testing curve.
