The crushing strength (also known as compressive strength) of a stone refers to its ability to withstand axial loads without fracturing. The stone with the maximum crushing strength is typically:

1. Granite
– Compressive Strength: 100–250 MPa (MegaPascals) or higher.
– Properties: Extremely hard, durable, and resistant to weathering.
– Uses: Heavy construction, bridges, dams, and monuments.
2. Basalt
– Compressive Strength: 150–300 MPa (one of the strongest natural stones).
– Properties: Fine-grained, volcanic rock with high density.
– Uses: Road construction, railway ballast, and reinforced concrete.
3. Quartzite
– Compressive Strength: 150–300 MPa (similar to granite but often harder).
– Properties: Metamorphic rock formed from sandstone; very tough.
– Uses: Flooring, countertops, and heavy-duty construction.
Comparison with Other Stones:
– Sandstone: 20–170 MPa (varies widely based on porosity).
– Limestone: 30–250 MPa (depends on 
e and purity).
– Marble: 70–140 MPa (softer than granite/basalt).
Conclusion:
Basalt and quartzite generally have the highest compressive strength among natural stones, closely followed by granite. For engineering applications requiring maximum load-bearing capacity, these are preferred choices.
