摘要：对广州某火灾大楼的幕墙密封胶进行现场检查与取样实验室检测，通过分析检测数据结果表明，过火区域密封胶碳化、脱胶严重，未过火区域密封胶质量状况良好。总结密封胶物理性能指标间存在相应关系，可为今后密封胶试验数据的准确性判定以及密封胶物理性能现场检测技术的开发提供参考。

Abstract：Field inspection and sampling laboratory testing of curtain wall sealant in fire building were carried out. The test data analysis results show serious carbonization and degumming of sealant in burnt area，sealant is in good condition in unburnt area. This paper summarizes the relationship between physical properties of sealant. It provides a theoretical basis for judging the accuracy of sealant test data and developing on-site testing technology of sealant physical properties in the future.
Key words：existing building curtain wall，burnt silicone sealant，physical property testing
