Limestone (hard)

Hard limestone is a sedimentary rock composed primarily of calcium carbonate minerals, typically calcite or aragonite. It is characterized by its durability and resistance to erosion, making it a dense and durable rock. Hard limestone forms over geological time through the accumulation and compression of marine organisms, such as coral and shells.

Predicting Los Angeles abrasion loss of rock aggregates …

Ballivy and Dayre (1984) found an inverse relation between UCS and LA abrasion loss for limestones, the degree of correlation being different for different types of limestone. The porous limestones indi-cated strong correlation, whereas the correlation for the massive, less porous limestones varied as a function of grain size.

Unveiling The Hardness Of Limestone: A Detailed Exploration

Limestone, composed mainly of calcite, ranks 3 on the Mohs hardness scale, meaning it resists scratching from a fingernail but yields to a copper penny or steel knife. The Mohs scale measures mineral hardness by comparing it to ten reference minerals. Limestone's hardness arises from its closely packed calcite crystals. A simple scratch test can verify its …

Limestone | Types, Properties, Composition, Formation, Uses

Limestone is a relatively soft rock with a Mohs hardness of 3, which means it can be easily scratched. It has a specific gravity of 2.7-2.9, which makes it less dense than most other rocks. It is typically soluble in acidic solutions, which is why limestone landscapes often feature caves, sinkholes, and other karst formations.
