摘要
选取海口地区常用原材料制作不同强度等级标准试件,测试不同龄期下试件的超声波声速值和抗压强度值,得到泵送混凝土强度与声速值相关性,建立泵送混凝土不同龄期超声测强曲线。
Taking different strength grade at concrete standard test block,measuring the ultrasonic velocity and the compressive strength under different ages. The experiment data were comparatively analyzed to reveal the correlation between the wave velocity of ultrasonic with pumping concrete strength,the district supersonic strength detection curve of pumping concrete is respectively established for 7 day ages and 28 day ages.
