The hardness of stone is measured by Mohs hardness as a unit of calculation, Mohs hardness in the 6~7 (F=14~20) are hard stone, such as Quartzite and Granite; Mohs hardness between 3 to 5 (F=8~14) belong to the medium-hard stone, such as Marble; Mohs hardness in 1~2 (F=2~6) are soft stone, such as limestone and dolomite etc.
Limestone is a carbonate sedimentary rock that is often composed of the skeletal fragments of marine organisms such as coral, foraminifera, and molluscs.Its major materials are the minerals calcite and aragonite, which are different crystal forms of calcium carbonate (CaCO 3).A closely related rock is dolomite, which contains a high percentage of the mineral dolomite, CaMg(CO 3) 2.
Limestone is a rock composed of calcium carbonate (CaCO 3).It is the rock type most commonly used to make crushed stone in the United States. It holds this position because it is widely available and suitable for a greater diversity of uses than any other type of rock.
Dolomite, also known as "dolostone" and "dolomite rock," is a sedimentary rock composed primarily of the mineral dolomite, CaMg(CO 3) 2. Dolomite is found in sedimentary basins worldwide. It is thought to form by the postdepositional alteration of lime mud and limestone by magnesium-rich groundwater. Dolomite and limestone are very similar rocks.

Calcite is a form of calcium carbonate, a type of calcium salt oxide with three atoms of oxygen bonded to one atom of calcium. Calcite binds with other compounds to create limestone which is used in construction. When using these substances as building materials, the differences between calcite and limestone become clear.
There are many different types of limestone formed through a variety of processes. Limestone can be precipitated from water ( non-clastic, chemical or inorganic limestone), secreted by marine organisms such as algae and coral (biochemical limestone), or can form from the shells of dead sea creatures (bioclastic limestone).
Rocks with hardness 1-3 are soft rocks from 3-6 are medium hardness rocks and 6-10 are hard rocks. The hardness of Limestone is 3-4 whereas its compressive strength is 115.00 N/mm 2. Streak is the color of rock when it is crushed or powdered. The streak of Limestone …
