A structure must be designed and built in such a way that, with an acceptable level of safety , it can resist all the forces to which it may be subjected during its construction and throughout the useful life period foreseen in the project. Throughout the “life” period of a structure, normal maintenance will be required to maintain proper condition, but rehabilitation operations will not be necessary. With the passage of time, however, it has been seen that reinforced concrete is more vulnerable than previously thought and its characteristics are altered by external agents, such as the growing pollution in our environment, the penetration of gases and water or contact with groundwater or soils with high sulfate content. Therefore, there are situations in which concrete repair becomes essential. Structural and non-structural concrete protection systems.
The EN 1504 standard – part 3, specifies the requirements for the identification, performance and safety of products and systems to be used for the structural and non-structural repair of concrete structures. These systems and products , when applied to a concrete structure, replace deteriorated concrete and restore its Antarctica Email List structural integrity and durability. If it is a non-structural repair, they restore its original shape and protect the structure to prevent future damage. Concrete restoration can be carried out in the following ways: • Applying mortar by hand • Filling with concrete or mortar • Increasing the reinforcement cover with mortar or concrete • Structural reinforcement by adding concrete or mortar .
Replacing deteriorated concrete • Spraying concrete or mortar To determine the method, the phases of the concrete repair process will be taken into account ; inspection, diagnosis, determination of the object of repair and selection of appropriate methods for repair. From this analysis, we have the following options: a) Assume a decrease in the function of the structure after recalculating b) Improve and reinforce, partially or totally, the concrete c) Partially or totally rebuild the concrete structure In most cases of concrete repair , it is usually necessary to use a system, not a single product, which usually consists of a combination of.
