摘要
对混凝土冻融损伤的红外热象特征进行了实验研究。结果表明,混凝土冻融损伤区域在红外热象图上呈“热斑”特征,根据“热斑”的温度范围和面积大小,可评定混凝土冻融损伤程度,其可靠性用超声波脉冲法作了验证,可为修复工程提供有价值的技术资料。
The infrared thermal image characteristics of freezing-thawing injury of concrete were studied. Ex-perimental results showed that the injured areas of a freezed-thawed concrete were indicated remarkably by thermal spots in an infrared image. Injury degree was evaluated according to their temperature ranges and areas. Test and evaluation reliability was verified by ultrasonic pulse method. It can provide valuable informations for building ren-ovation.
