Limestone mined in Haryana is used in the production of cement.
Cement is a binding agent that is used to hold together other materials, such as sand and gravel, to form concrete. It is made by heating limestone and clay to a high temperature, which causes them to react and form a new substance called clinker. The clinker is then ground into a powder and mixed with water to form cement.
