一、概况利用回弹仪测量混凝土表面硬度来确定混凝土的强度,是混凝土质量非破损检测方法之一。由于回弹仪具有结构简单、轻巧、操作方便和测试迅速等优点,因而已被人们广泛应用。但因回弹仪是一种机械式的测强仪器,它的质量及其稳定性较难达到一致,这就给测试带来一定的误差,引起了研究者的争议。1965—1967年期间,RILEM的混凝土非破损试验组作了国际调查,调查结果认为:用回弹仪检验混凝土的均匀性和进
I. Overview The use of a rebound meter to measure the surface hardness of concrete to determine the strength of concrete is one of the methods for the detection of non-destructive quality of concrete. Because of its advantages such as simple structure, light weight, convenient operation and rapid testing, the springback device has been widely used by people. However, because the rebound instrument is a kind of mechanical strength measuring instrument, its quality and its stability are difficult to reach the same, which brings certain errors to the test, causing the researchers’ controversy. During the period from 1965 to 1967, the RILEM’s concrete non-breakage test group made an international survey. The survey concluded that the use of a rebound tester to check the uniformity and advancement of concrete
