Proposed standardization changes in the assessment of concrete durability

The article presents the concept of concrete durability based on the system of concrete resistance classes to ERC exposure included in the proposed standardization documents (EN 206-1 together with EN 206-100 and Eurocode 2). According to the ERC concept, the performance properties of concrete are tested using recognized test methods, and the results are assessed on the basis of criteria independent of the composition of the tested concrete. The ERC durability concept is open to new technical and standardization solutions in the field of concrete composition (new additives) and cement and should replace the generally applicable prescriptive solutions. This solution is important from the point of view of reducing the emissions of the cement industry (production of multi-component cements and the use of new non-clinker main ingredients) and reducing the carbon footprint of concrete (CO2 reduction classes of concrete according to prEN 206-1)
