混凝土内部缺陷能力比对样品制备研究

Study on sample preparation for comparison of concrete internal defect capability

为完成混凝土内部缺陷(超声法)能力比对项目,制备了一批混凝土试样,验证了混凝土试样的稳定性和均匀性。结果表明:能力比对样品的稳定性和均匀性均符合《能力验证样品均匀性和稳定性评价指南》(CNAS-GL03)中规定的要求。

In order to complete the project of capability comparison of concrete internal defects(ultrasonic meth⁃od),a number of concrete samples are prepared,and the stability and uniformity of concrete samples are veri⁃fied.The results show that the stability of ultrasonic wave and compressive strength,and the uniformity of ultra⁃sonic wave are in accordance with the requirements of CNAS-GL03.
