I am interested in concrete testing, compressive strength. The new standard EN 12390-1:2021 came out, and before it was standard EN12390-1:2013. Please could you tell me the difference between these two standards. What are the news that the new standard 2021 gave. I do not understand. Because by comparing these two standards, I could not see anything significant that would affect the examination process itself. Please help. Thanks in advance
Can help me this, someone ?
