Application Of High Performance Concrete Rebound Detection Technology In HeBei

In recent years,China's high-rise buildings,large span bridge construction development is rapid,the application of high performance concrete is more and more widely,therefore,to strengthen quality supervision and management of concrete structure is particularly important.It is necessary to strengthen the supervision and management of engineering quality safety.It is an important way to improve the regulation efficiency to create a new type of supervision and management mode.At all levels,quality supervision stations should constantly improve management technology,strengthen supervision and detection technology by establishing certain management system,and constantly improve the professional quality of supervisors.At the same time,we should constantly strengthen the theoretical summary and research of technology,and promote the continuous improvement and development of engineering quality supervision.Concrete member entity detection is an indispensable link in engineering quality and safety supervision,and nondestructive testing technology in the component entities detection plays an important position,sign recognition and acceptance of construction quality,construction of the cohesion of different operating procedures and quality control during construction cannot leave the concrete nondestructive testing technology.The quality control of concrete components has always been one of the important indexes in engineering quality management,and because of the particularity of concrete components,the nondestructive testing methods of the concrete components are particularly important.Combining with the concrete nondestructive testing technology in the application of project quality management and promotion in the field of engineering in hebei region,high performance concrete for intensity level in more than 60 mpa high-performance concrete,concrete with hebei region common materials preparation,using the rebound method and ultrasonic rebound synthesis method,analysis of its established for hebei region rebound testing rebound strength curve of high performance concrete,and connecting with the concrete carbonation depth,curing conditions and other comprehensive analysis,the factors which influence for the application of high performance concrete in our region and provide guidance to the corresponding engineering quality inspection and supervision.
