🧪 Standards Basis (for reference in lab use)

• Fine sieves (< 4.75 mm): max mass = 7 kg/m² × effective area.
• Coarse sieves (≥ 4.75 mm): max mass = 2.5 × opening(mm) × effective area(m²).
• Effective areas used (ASTM C136/C136M-19, Table 1 / Note 6): 200 mm ≈ 0.0285 m², 300 mm ≈ 0.0670 m².
• Adequacy check (§8.4) is mentioned in the README_Ali4Concrete file for field practice.

This repository only provides helper calculations; the official standard controls the method.

▶️ Quick Start

1. Open the notebook: Ali4Concrete_C136_Overload_Limits_Final.ipynb in Jupyter or GitHub preview.
2. Run all cells. You will get a table and a quick comparison plot for 200 mm vs 300 mm frames.
3. Export fresh CSV/Excel if needed.
