At present, the application of high performance concrete in super high-rise building engineering structure is more and more extensive. The mix proportion of high-strength concrete is the basic variable of concrete, and the rebound detection of building structure is carried out. On this basis, the design method of building pressure matching is proposed. Due to the large error of the estimated value of the strength test curve unified by the whole country, in a new project in Xi’an, the rebound method and core drilling method are carried out on several concrete members, and it is concluded that the test results of rebound method and core drilling method with different strength levels are quite different. In view of the difference of test results of mix proportion rebound method of high-strength concrete of super high-rise buildings in Xi’an area, the correction method of rebound difference of different strength levels is put forward.
