Inspection and repair methods on frost damage of concrete based on evaluation of scaling using gloss meter

本研究针对混凝土的结垢等霜冻损伤，利用薄铝箔光泽度计对结垢进行评价，探讨混凝土霜冻损伤的检测与修复方法。从光泽度中得到表面粗糙度，并从表面粗糙度中估计出结垢量。根据实验结果，提出了从光泽度估算混凝土减重的方程，并根据实验结果提出了结垢进度预测方程。研究了老化混凝土的适当修复方法，并对寒区的实际结构进行了现场调查，验证了我们提出的方法。调查结果表明，该方法测量的尺度状态与基于目测的RILEM标准方法的结果相匹配。

In this study, we dealt with frost damage of concrete such as scaling, and investigated the inspection and repair methods on frost damage of concrete based on evaluation of scaling using gloss meter with thin aluminum foil. It was obtained surface roughness from the glossiness, and estimated amount of scaling from the surface roughness. According to the results, we proposed the equation for estimation of concrete weight loss from glossiness, and also proposed the equation for progress prediction of scaling based on results of experiments. We studied appropriate repair methods for deteriorated concrete and carried out field survey of actual structures located in cold region for verification of our proposed methods. The survey results showed that the state of scaling measured by the proposed method matched the results by the RILEM standard method based on visual observation.
