Quick Answer: How Hard Is Limestone Rock

2021-9-26 · Is limestone a strong rock? Although relatively soft, with a Mohs hardness of 2 to 4, dense limestone can have a crushing strength of up to 180 MPa. For comparison, concrete typically has a crushing strength of about 40 MPa. Although limestones show little variability in mineral composition, they show great diversity in texture.
