混凝土结构的保护和修复已成为一个重要的市场。例如，桥梁的维护费用每年超过10亿美元。所有类型建筑物的维修费用总额可假定高于每年约200亿美元。其中很大一部分费用花在混凝土结构的维修和保护上。与建造新结构所花费的工作量相反，维修和保护市场随着现有基础设施的老化而大幅增长。混凝土结构维修和保护的新方法和新材料的广泛发展导致了对这类工程和产品的标准的需要。表1显示了新的EN 1504的结构，包括10个主要标准和61个测试方法标准。如表1所示，该系列标准集中在第2至7部分，这些部分是对用于混凝土结构保护和维修的不同产品和系统进行CE标志的基础。然而，EN 1504的第9部分同样重要，它描述了产品的使用原则，这些原则将在以下各节中进行解释。第1部分给出了定义，第8部分规定了产品的质量控制，第10部分给出了现场应用和工程质量控制的一般指南。为了允许对产品进行CE标记，已经发布了描述产品不同性能的测试方法的61个标准。这些标准确保对产品的测试符合欧洲使用的保护和修复混凝土结构的所有产品的相同标准。
Protection and repair of concrete structures has become an important market. As an example the costs for the maintenance of bridges are higher than 1 billion $ per year. The total costs for maintenance of all types of buildings can be assumed to be higher than about 20 billion $ per year. A significant part of this costs are spent on repair and protection of concrete structures. On the contrary to the amount of work spent on building new structures, the market of repair and protection has grown considerably as the age of the existing infrastructure is increasing. The extensive development of new methods and materials for the repair and protection of concrete structures has led to the need of standards for such works and products. Table 1 shows the structure of the new EN 1504, consisting of 10 main standards and 61 standards for test methods. As shown in table 1 the series of standards is focused on parts 2 to 7, which are the basis for CE marking of the different products and systems to be used for protection and repair of concrete structures. However, part 9 of EN 1504 is not less important, describing the principles for the use of the products, which are explained in the following sections. Part 1 gives definitions, part 8 regulates the quality control of the products and part 10 gives a general guideline for site application and quality control of the works. To allow CE marking of the products 61 standards describing test methods for the different properties of the products have been published. These standards ensure that testing of the products are according to the same standards for all products for protection and repair of concrete structures used in Europe.
