Limestone - Wikipedia

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.

Limestone Minerals Crushing in Mining - JXSX Mine

Limestone is a sedimentary rock composed mostly of the mineral calcite and comprising about 15% of the Earth’s sedimentary crust. It is a basic building block of the construction industry (dimension stone) and a chief material from which aggregate, cement, lime and building stone are made. 71% of all crushed stone produced in the U.S. is either limestone or dolomite.

Shear Strength Characteristics of Crushed Limestone ...

crushing increases with an increase in normal stress but major crushing occurs during shear. The grain size distribution of the sample undergoes a continuous change with the application of shear and normal stress. For same particle size and gradation, shear strength of sandstones and gravel are different at normal stress. At high normal stress shear strength of gravel is more than sand stone ...
