对回弹法检测混凝土抗压强度的讨论

在我国,回弹法检测混凝土强度无疑有历史功绩,当前出现的问题:一是因为混凝土材料组分更加复杂;二是人们因对回弹法缺乏正确认识而使用不当.用回弹法可有效地检验混凝土结构的匀质性,对强度只能是辅助的参考;碳化层厚度和同弹值大小并没有关系,用碳化层厚度对回弹值换算的强度进行修正,在理论上和实践上都是欠缺的.影响回弹值的主要因素是强度和表面状况.

Discussion on using rebound method to test compress strength of concrete

Merits of Rebound Method for testing strength of concrete is incontrovertible historically in China.Emergence of problems in recent years is due to that ingredient of concrete is more complicated,and that operation had not been canonical because of a lack of correct cognition to rebound method.The rebound method can be used for tested uniformity of concrete structure efficaciously but accessorial estimate for strength of concrete.The rebound value is nothing to do with thickness of carbonate layer,so that t...
