回弹法检测实体混凝土抗压强度研究

Study on inspection of concrete compressive strength by rebound method

通过用工程实体结构上得到的混凝土"标准芯样"抗压强度值替代混凝土立方体试块的抗压强度值,建立了混凝土芯样抗压强度值、回弹平均值及碳化深度值三者之间的回弹测强曲线。该曲线在工程实体混凝土强度检测中具有更高的实用价值。

Based on the compressive strength of the standard core from the project which replaces the compressive strength of the concrete teat cube,the paper presents the rebound curve of the core sample compressive strength,rebound strength and carbonization depth.The curve is more practical in the inspection of project concrete compressive strength.
