超声波测早期混凝土强度探讨

RESEARCH ON ULTRASONIC TESTING OF THE STRENGTH OF EARLY-STAGE CONCRETE

用超声波在非常早期隔模检测混凝土强度,探讨超声脉冲传播速度与早期强度之间的关系.试验结果表明,早期脉冲传播速度与强度之间的相关性好于后期.

Early-stage concrete strength was tested by ultrasonic technique from the outside of formwork , the relationship between ultrasonic pulse speed and early-stage strength was discussed. Testing results showed that correlation of pulse speed with strength at early stage is superior to that at later stage.
