The interface bonding quality is critical to the repair effect of repaired cementitious materials. In present, there is no proper method to accurately evaluate whether the interface can establish the effective mechanical connection. This work proposed a method to visualize the interface bonding effect of cementitious materials repaired zone. The volume images on three repaired mortars with different bonding areas during loading process were obtained via in-situ X-ray computed tomography. The digital volume correlation (DVC) was employed to analyze the volumetric strain distribution of samples based on the obtained images. As there is no constraining in de-bonding area, a greater deformation occurs in the loading process than in the bonded area. Therefore, the area without a mechanical bond in the repaired mortar can be visualized through the strain mutation in the DVC strain contour. The results show that the strain mutation area detected in the DVC results corresponds well with the artificial de-bonding area, indicating that this method can detect the de-bonding area in the repaired mortar.

界面的粘结效果对水泥基材料的修复至关重要,但是目前没有合适的方法评估粘结材料是否在界面建立有效粘结。本工作提出一种方法对水泥基样品修复区的粘结效果进行可视化分析。对3个具有不同粘结面积的砂浆样品开展X射线计算机断层扫描原位轴压试验并获取加载过程中的体图像,然后采用数字体相关法(DVC)对变形前后的体图像进行相关计算。未粘结区域不受粘结剂约束,加载过程中会产生较粘结区域更大的变形,通过DVC应变图中出现的应变突变可以检测出样品中未建立有效粘结的区域。结果表明,应变图中检测出的未建立有效粘结区域与实际的未粘结区域对应良好,说明该方法能检测定位出修复后的样品中的无粘结区域。

界面的粘结效果对水泥基材料的修复至关重要,但是目前没有合适的方法评估粘结材料是否在界面建立有效粘结。本工作提出一种方法对水泥基样品修复区的粘结效果进行可视化分析。对3个具有不同粘结面积的砂浆样品开展X射线计算机断层扫描原位轴压试验并获取加载过程中的体图像,然后采用数字体相关法(DVC)对变形前后的体图像进行相关计算。未粘结区域不受粘结剂约束,加载过程中会产生较粘结区域更大的变形,通过DVC应变图中出现的应变突变可以检测出样品中未建立有效粘结的区域。结果表明,应变图中检测出的未建立有效粘结区域与实际的未粘结区域对应良好,说明该方法能检测定位出修复后的样品中的无粘结区域。

The interface bonding quality is critical to the repair effect of repaired cementitious materials. In present, there is no proper method to accurately evaluate whether the interface can establish the effective mechanical connection. This work proposed a method to visualize the interface bonding effect of cementitious materials repaired zone. The volume images on three repaired mortars with different bonding areas during loading process were obtained via in-situ X-ray computed tomography. The digital volume correlation (DVC) was employed to analyze the volumetric strain distribution of samples based on the obtained images. As there is no constraining in de-bonding area, a greater deformation occurs in the loading process than in the bonded area. Therefore, the area without a mechanical bond in the repaired mortar can be visualized through the strain mutation in the DVC strain contour. The results show that the strain mutation area detected in the DVC results corresponds well with the artificial de-bonding area, indicating that this method can detect the de-bonding area in the repaired mortar.
