混凝土加固改造用建筑结构胶粘剂质量检测方法

Quality Testing Method for Building Structural Adhesives Used for Concrete Reinforcement and Renovation

针对混凝土加固改造用建筑结构胶粘剂质量检测方法进行研究。通过过滤、离心、杂质吸附等环节,对选定的建筑结构胶粘剂样本进行预处理,制备质量检测样品溶液,采集制备得到胶粘剂样品的液相色谱数据,绘制胶粘剂样品的标准曲线,并计算得出每份胶粘剂样品的检出限。根据检测得到的混凝土加固改造用建筑结构胶粘剂样品的检测线,得出每种建筑结构胶粘剂的物质含量,与标准限量值对比得知,仅11#胶粘剂未满足质量标准,与检测胶粘剂的实际应用效果高度一致。混凝土加固改造用建筑结构胶粘剂质量检测方法得出的检测结果准确度较高,在混凝土加固改造工程中,建筑结构胶粘剂的应用具有良好的推广意义。

The quality testing method for building structural adhesives used for concrete reinforcement and renovation are studied.Through filtra-tion,centrifugation,impurity adsorption and other processes,the selected building structure adhesive samples are preprocessed to prepare a quality testing sample solution.The liquid chromatography data of the prepared adhesive samples are collected,and the standard curve of the adhesive sam-ples is drawn.The detection limit of each adhesive sample is calculated.Based on the detection lines of building structural adhesive samples used for concrete reinforcement and renovation,the material content of each type of building structural adhesive is obtained.Compared with the standard limit value,it is found that only 11 # adhesive doesn't meet the quality standard,which is highly consistent with the actual application effect of the testing adhesive.The accuracy of the test results obtained by the test method for the quality of building structural adhesives used for concrete reinforcement and renovation is high,and the application of building structural adhesives in concrete reinforcement and renovation projects has good promotion sig-nificance.
