How does the compressive strength of granite compare to concrete in large planters?

When selecting materials for large planters, compressive strength is a critical factor for durability and longevity. Granite, a natural stone, boasts an impressive compressive strength ranging from 100 to 300 MPa, making it highly resistant to cracking under heavy loads. Concrete, on the other hand, typically has a compressive strength of 20 to 40 MPa for standard mixes, though high-performance variants can reach up to 80 MPa.

Granite's superior compressive strength makes it ideal for large planters exposed to extreme weather or heavy use, as it resists deformation and wear over time. Concrete, while less robust, offers versatility in design and cost-effectiveness, especially when reinforced.

For outdoor applications where structural integrity is paramount, granite outperforms concrete. However, concrete remains a practical choice for budget-conscious projects with moderate load requirements. Understanding these differences ensures you select the best material for your large planter needs.
