Cement is made primarily from crushed limestone and clay or shale, which are heated in a kiln to form clinker. The clinker is then ground into a fine powder and mixed with gypsum to create the final product. This process involves high temperatures and contributes to cement's essential properties for use in construction and infrastructure. Additional materials may also be added to enhance performance or adjust setting times.

Concrete is made from cement and other cementitious materials such as fly ash and slag cement, coarse aggregate made of crushed stone, fine aggregate such as sand, water, and chemical admixtures. For more information please visit the related link.
Concrete IS nature, the aggregate is crushed rock, the cement is made of natural lime and clay, mix these together with water and you get concrete.

Cement is primarily made from limestone and clay, which are sourced from quarries. The raw materials are crushed, mixed, and then heated in a kiln to produce clinker, which is then ground into a fine powder to create cement. Additional materials, such as gypsum, may be added to control the setting time. The manufacturing process involves significant energy use and contributes to carbon emissions.

Limestone is crushed and baked at high temperatures to produce the main ingredient for Portland cement.
Sidewalks are made of concrete, which is not a rock. Concrete is a man-made construction material composed of Portland cement, various crushed rocks, sand and water.
Concrete is made from cement and other materials such as fly ash and slag, coarse aggregate made of crushed stone, fine aggregate such as sand and water. The aggregates are used to form the paste, while the sand or cement keeps it from wearing out easily, and the water to make it easy to smooth out.

Limestone is the sedimentary rock that is used to make cement. Some limestone is made of old coral reefs that have been buried by deposits.
No, concrete is not a rock. Concrete is a man-made material composed of a mixture of cement, water, and aggregates such as sand and gravel. Rocks are naturally occurring solid materials composed of minerals.
