What is the compressive strength of limestone? Thank you
Limestone is a carbonate rock mainly composed of calcite minerals, usually as a mineral material, and the commodity is limestone. It is widely used in many fields such as construction, metallurgy, chemical industry, light industry, food, petroleum, agriculture and so on.
The mineral composition is mainly calcite. The chemical composition of calcite CaCO3 Theory: CaO56.04%, CO243.96%, is the three party system, the three party is often Chengfu scalenohedral and rhombohedral crystal, a collection of druse, granular, stalactitic, oolitic or dense, colorless or white, shiny glass, hardness 3, density of 2.6 ~ 2.8t/m3, in severe foaming dilute hydrochloric acid.
To 2.7t/m3, the compressive strength, vertical bedding direction generally 60 ~ 140MPa, parallel bedding direction generally 50 ~ 120MPa, loose coefficient generally 1.5 ~ 1.6.
