⬆️ density comparison (kg/m³ or lb/ft³) — worldwide mixes
📌 factors & standards (USA / global)
- USA (ACI 301/318): normal weight = 145 lb/ft³ (2320 kg/m³). Lightweight concrete 90–120 lb/ft³, heavyweight up to 210 lb/ft³ (with steel punch or barite).
- Europe (EN 206): density classes D1.0–D2.0 for lightweight, D2.1–D2.5 for normal, D2.5+ for heavyweight.
- Influence of rebar: typical 1–2% by volume adds 3–5% weight. Moisture content can increase weight by 2–4%.
- Aggregate type: granite ~2.7 t/m³, limestone ~2.5 t/m³, lightweight expanded clay ~1.2 t/m³.
