摘要

This paper in detail introduces basic principles and technical development process of inspecting the material strength of high performance concrete by rebound method and Ultrasonic-rebound combined method. The strength-inspected curves of high performance concrete in Beijing region are given by using above mentioned two methods. Existing problem that 2.207J rebound device could not be used to inspect the strength of concrete at grades 50MPa and above, has been solved. This article is one of the research results in "Technical specification for strength testing of high strength concrete"JGJ/T 294-2013 during compiling, which can be used in inspecting the material strength of high strength concrete in Beijing region.
