检测混凝土强度方法及改进措施

Abstract With the development of China's construction industry various types of buildings have a rapid development in the city andthe concrete has been widely applied to these buildings. Concrete is a structural material. In recent years it is constantly updated in termsof variety intensity level purpose etc. and the concrete technology has made great strides. Concrete quality directly affects the safety andreliability of the project and the compressive strength is an important indicator to assess the quality. In Structural Testing course there aremany detection methods for concrete strength. The paper discusses the main factors influencing the accuracy of various detection methods which provides a reference for the detection of concrete.院混凝土 超声回弹 抗压强度Key words concrete ultrasonic rebound compressive strength中图分类号院TU37 文献标识码院A 文章编号院1006-4311（2014）23-0119-02
