| 摘 要： | 回弹法检测混凝土抗压强度,已经成为我国混凝土工程现场原位检测的最有效、最方便的检测方法。但当用回弹法检测评定矿物掺和料混凝土强度时,常常遇到碳化深度异常、回弹值异常等情况,造成评定结果不满足设计要求。文章从矿物掺和料混凝土水化机理分析产生上述现象的原因,提出用回弹法检测评定矿物掺和料混凝土强度时应注意的问题。

| Abstract: | The rebound method for inspecting the compressive strength of concrete has become the most effective and convenient method in China for on-suit inspection of concrete works. However, problems of abnormal carbonation depth and abnormal rebounding value often occur and result in the evaluation results do not meet design requirements. This paper analyzes causes of above conditions from the hydration mechanism of the concrete with mineral additives and proposes attentions when the strength of concrete with mineral additives is inspected and evaluated with the rebound method |
