Building with stone: Limestone - Stone Specialist
Portland and Bath stone generally exhibit compressive strengths of between 30 and 50MPa (megaPascals), which is similar to good quality concrete and more than sufficient for most purposes. Limestone is typically impressively strong under compression, like concrete, but exhibits flexural strengths of around one tenth of the compressive strength.

Limestone - Wikipedia
The density of limestone depends on its porosity, which varies from 0.1% for the densest limestone to 40% for chalk. The density correspondingly ranges from 1.5 to 2.7 g/cm 3. Although relatively soft, with a Mohs hardness of 2 to 4, dense limestone can have a crushing strength of up to 180 MPa. [13]
