EN 206 Concrete Mix Design
Proportion concrete to EN 206: choose a strength class and exposure class, and the calculator shows the durability limiting values and a preliminary absolute-volume mix. Confirm by trial batches.
EN 206:2013+A2:2021
Durability: limiting values shown are the EN 206 recommended set. National annexes (BS 8500, DIN 1045-2) may differ — verify for your project.
