Background – Transferability of testing methods and requirements to secondary building materials

-> Can the test methods that have proven themselves with natural primary building materials be applied to secondary building materials?
-> Are the requirement values based on experience with natural primary building materials transferable to secondary building materials?
-> What differences are to be taken into account in the testing and to what can these be attributed?
-> Do differences in comparison to natural primary building materials limit the serviceability of secondary building materials?
