回弹法检测混凝土强度时不同测强曲线的比较

在混凝土强度现场检测方法中,回弹法因其简便、快捷得到广泛应用;回弹法测试精度问题是新建工程验收和既有建筑加固改造常常遇到的问题。本文通过对不同测强曲线芯样修正前后检测结果的分析比较,对如何保证混凝土强度回弹法检测精度以及仲裁检测提出合理建议。

Compare of Different Concrete Intensity Curves Which are Measured by the Rebound Method

Among the site-testing techniques of the concrete intensity, the rebound method has been widely used because of its easiness; the testing precision problem of rebound method is the common problem in acceptance of works and renovation or reinforce project. The different testing results before and after adjustment of samples of intensity curves are analyzed and compared in this paper, the reasonable advises about how to ensure the testing precision of rebound method and the arbitration test are put forward.
