EN 1504第4部分规定了强化材料与现有混凝土结构的结构粘结的结构粘结产品和系统的识别，性能（包括耐久性）和安全性的要求，包括: 1）将钢板或其他合适材料（如纤维增强复合材料）的外部板材粘合到混凝土结构的表面，以加强目的，包括在这些应用中层压板材。 2）硬化混凝土与硬化混凝土的结合，通常与修复和加固中预制单元的使用有关。 3）使用粘合剂接合剂将新拌混凝土浇筑到硬化混凝土中，形成结构的一部分，需要复合地起作用。 本标准本部分的性能要求可能不适用于极端环境条件下的高度专业化应用，例如低温使用，也不包括特殊情况，如意外的影响，例如由于交通或冰，或地震负荷，具体的性能要求将适用

This Part 4 of EN 1504 specifies requirements for the identification, performance (including durability) and safety of structural bonding products and systems to be used for the structural bonding of strengthening materials to an existing concrete structure, including: 1) The bonding of external plates of steel or other suitable materials (e.g. fibre reinforced composites) to the surface of a concrete structure for strengthening purposes, including the laminating of plates in such applications. 2) The bonding of hardened concrete to hardened concrete, typically associated with the use of precast units in repair and strengthening. 3) The casting of fresh concrete to hardened concrete using an adhesive bonded joint where it forms a part of the structure and is required to act compositely. The performance requirements in this Part of this Standard may not be applicable to highly specialised applications in extreme environmental conditions, e.g. cryogenic use, nor do they cover specialised circumstances such as accidental impact, e.g. due to traffic or ice, or earthquake loading where specific performance requirements will apply.
