Changes made: a 28-row excerpt (six mixes) was selected from the 727-row source table and
re-formatted into the Open3DCP flat schema. Constituent masses (kg/m3) and the GWP figure are
copied unchanged; compressive strength was converted psi -> MPa and slump in -> mm. Underlying
values are otherwise unchanged; the full table is not redistributed (download it from the repo).
