摘要
粗糙处理后的老混凝土表面具有分形特征.通过自制粗糙度测定仪,用简单分形方法评价老混凝土表面粗糙度,并与常规测试方法进行对比.数据表明,分形维数-D和平均灌砂深度-h二者回归线性良好,可以做为混凝土的精糙度评价指标.该测量仪操作简单、使用方便,适合实际加固工程中老混凝土表面粗糙度的测量.
After some treatment, the old concrete surface is rough and has some fractal characteristics. Using a special instrument, the old concrete surface roughness is measured and the result is compared with other measuring method. The practice proves that the method is simple and effective in concrete roughness measuement, and suitable for application in practical concrete strengthening projects.
