长期来,如阿使结构不破坏,而直接测得结构混凝土强度值,一直是人们研究的课题。目前世界上为达到这种目的而采用的有回弹法、贯入法、拔出法、共振法、超声法、放射性法、中子法、磁感法、电测法、微波吸收技术、声发射技术和综合法等。由于回弹法设备轻便,无需电源,影响因素相对来说比较少,近三十年来被各国广泛采用。但大多数国家用于检查混凝土的均匀性以及用于一种混凝土与另一种混凝土的对比试验上,对于混凝土的强度值只能粗略地表示。我
For a long time, if the structure of Azerbaijan is not destroyed, the strength value of structural concrete measured directly has always been the subject of research. Currently used in the world for this purpose are rebound method, penetration method, pull-out method, resonance method, ultrasonic method, radioactive method, neutron method, magnetic induction method, electrical measurement method, microwave absorption technology, and sound. Launch technology and comprehensive law. Since the rebound method is portable and does not require power, the impact factor is relatively small and has been widely adopted by various countries in the past 30 years. However, most countries are used to check the homogeneity of concrete and for comparison tests of one type of concrete with another, the strength value of concrete can only be expressed roughly. I
