The open concrete-data landscape

Example entries

Worked Open3DCP records converted from public, openly-licensed academic and national datasets — each shows the source's data classes and storage medium, and how it re-formats into the Open3DCP flat schema.

The national flywheel. Shared open production data raises the production value of construction — a national flywheel for development. Concrete data is scattered across benchmarks, national repositories, and standards bodies in incompatible shapes (flat vs relational vs file-based) and bases (kg/m³ vs mass-%). Open3DCP is the connective layer spanning the full digital twin: quarry → mix → 3DCP process → fresh rheology → hardened mechanical → durability → interlayer bond → embodied carbon → strength over decades.

Examples

UCI Concrete Compressive Strength →

CC BY 4.0 cast concrete

A flat kg/m³ benchmark (Yeh 1998). Exact kg/m³→mass-% projection; fidelity 96.7/A. Fills mix-design + hardened + multi-age; 3DCP/process/durability stay null.

RILEM TC 304-ADC ILS-mech →

CC BY 4.0 3D-printed

A multi-national relational SQLite of printed concrete. Denormalized + aggregated to mean±std-dev/n; shows print anisotropy (orientation) + process — the columns UCI leaves empty.

Coverage — each source lights up a slice; Open3DCP spans the whole

¹ commercial premix — w/b and yield stress captured, constituent dosages not disclosed. The gaps between slices are the connective-layer argument: no single source spans quarry → decades; the union does.

Storable vs reference-only

The rule: store only when the license clearly permits redistribution — CC BY 4.0, CC0, US-government public domain, or GODL-India — with attribution. Anything copyrighted, registration-gated, or unclear is reference-only and cited respectfully.

National map

Open concrete & materials-data efforts Open3DCP can interoperate with: USA — NIST (MGI; Federal LCA Commons, storable), UCI (CC BY 4.0), ACI (reference). International — RILEM TC 304-ADC (the 3DCP anchor; ILS-mech storable), NOMAD (FAIR exemplar). Germany — BAM + NFDI-MatWerk; Zenodo deposits CC BY 4.0. Japan — NIMS MatNavi (gated, reference), JCI–JACT (CC BY 4.0). China — National Materials-Genome stack (gated, reference); CAS ScienceDB (storable platform). South Korea — KISTI DataON. India — GODL-India permits redistribution (and IIT Madras contributes to RILEM ILS-mech). Russia — GOST (method codes only). Provenance (doi / source_citation / lab_name) is preserved on every row.
