摘要
简要介绍了国内外对混凝土粘结面粗糙度评定的方法,在此基础上提出了用一种自制的粗糙度测定仪进行混凝土粗糙度测定的方法,并针对该测定仪提出了多元线性回归法对人工凿毛混凝土面进行粗糙度评定的方法,该方法简便、快速、高效,能够有效地在实际工程中应用。
This paper summarizes the evaluation methods of the concrete surface roughness both at home and abroad. Based on these,a device is introduced to measure roughness of concrete surface,and a method is put forward to evaluate the roughness of a kind of artificial chiseling concrete surface,which is the multiple linear regression. The method of evaluation is simple and fast,and it can be applied to the actual engineering effectively.
