| 摘 要： | 结合具体工程案例,对超声-回弹法检测现场结构砼强度结果判定需要注意的问题进行探讨,认为超声-回弹综合法测定的结构混凝土强度,根据标准规定应是推定强度,不能作为判定强度是否合格的唯一依据.建议用非破损方法检测结构砼强度时,至少采用2种以上方法检测,并重视早期砼表面碳化深度过大对检测结果的影响,防止误判.

| Abstract: | Combining with the practice of engineering project,this paper discussed some problems need to attention when inspecting strength of structural concrete with ultrasonic-rebound combined method.The strength brought out by this method was the calculation strength.It could not be the only standard of judging whether the strength is qualified or not.It was suggested that more than two methods should be used when inspecting strength with non-destructive test.The influence of early-aged concrete carbonation depth ... |
