So Ne-012 [repack] -

The 2022 revision emphasizes modern concrete technologies and rigorous quality control. Key areas include: 1. Concrete Composition and Materials

Instead of relying solely on traditional compressive strength classes (e.g., C16/20, C25/30), NE 012/1 encourages specifying concrete based on environmental exposure classes. These classes (e.g., XC, XF, XS) define how the concrete will behave under specific conditions, such as: so ne-012
