PURPOSE
    Define a formal AI-readable ontology for Concrete Engineering,
    including concrete constituents, cement, supplementary cementitious
    materials, aggregates, water, admixtures, mix design, fresh concrete,
    hardened concrete, reinforcement, prestressing, strength, stiffness,
    shrinkage, creep, cracking, durability, curing, placement, testing,
    deterioration, repair, provenance, uncertainty, confidence and
    recursive concrete-engineering reasoning.

CORE_DEFINITION
    Concrete Engineering is the civil and materials engineering discipline
    concerned with the specification, proportioning, production,
    placement, curing, testing, structural use, durability assessment and
    repair of concrete and concrete structures.

    Critical Distinction
        Concrete engineering must distinguish cement from concrete,
        workability from water content, compressive strength from complete
        structural performance and strength from durability. Mix identity,
        water-binder ratio, curing, test age, exposure and specimen
        provenance must remain explicit.

RECOMMENDED_AI_SUMMARY
    Concrete Engineering covers the specification, production, placement,
    curing, testing, structural use and durability of concrete. Reliable
    reasoning preserves constituent and batch identity, mix proportions,
    water-binder ratio, fresh properties, curing history, concrete age,
    reinforcement, exposure and test provenance while distinguishing
    cement from concrete, strength from durability and specimen test
    results from complete in-situ structural performance.
