How does concrete outdoor ottoman aggregate size impact load capacity?

The aggregate size in a concrete outdoor ottoman plays a crucial role in determining its load capacity and overall durability. Larger aggregates, such as crushed stone or gravel, provide greater structural integrity but may reduce surface smoothness. Smaller aggregates, like sand, create a finer finish but may compromise strength if not properly reinforced.

For optimal load-bearing performance, a balanced mix of coarse and fine aggregates is recommended. Coarse aggregates (10-20mm) enhance compressive strength, while fine aggregates fill gaps to prevent cracking. Additionally, the cement-to-aggregate ratio and proper curing significantly influence the final product's weight tolerance.

To maximize longevity, consider using fiber reinforcement or steel rebar for heavy-duty applications. Always test prototypes under realistic weight conditions before finalizing your design. By carefully selecting aggregate sizes and proportions, you can create a concrete ottoman that combines aesthetic appeal with exceptional load-bearing capacity.
