Non-destructive evaluation (NDE) methods used for condition assessment of concrete structures

Abstract

As an integral part of the construction industry, concrete is an important part of the building materials industry, as well as an important material for infrastructure and engineering construction projects. It is widely used in various industries. In recent years, with the improvement of the quality awareness of the whole people, the engineering quality inspection has also received more attention. The previous concrete quality inspection methods have different degrees of damage to the original structure. This paper focuses on the state of concrete structure and its detection method, and introduces the EDN technology. At the same time, through comparison, practical experiment, theoretical research and other research methods to describe EDN technology. Based on the research results, it is concluded that ECN technology can provide a more comprehensive concrete quality report, which is beneficial to the maintenance, repair and restoration of Bridges and old buildings, and help engineers use.
