Products and systems for the protection and repair of concrete structures - Test methods - Part 3: Determination of early age linear shrinkage for structural bonding agents
用于混凝土结构保护和修复的产品和系统 - 试验方法 - 第3部分:结构粘结剂早期线性收缩的测定
This European Standard specifies a method for the determination of the early age linear shrinkage of structural bonding agents covered by EN 1501-1 and EN 1504-4. It describes the procedures for the measurement of linear shrinkage from initial gel of polymer, in the form of unrestrained thin strips less than 10 mm in thickness. It is intended for measurement of early age shrinkage, for example up to 24 hours.
