Concrete is one of the most ubiquitous materials on the planet, a staple of construction around the world. It starts as a mixture of water and portland cement, which forms a paste to which materials such as sand, gravel or crushed stone are added. The paste binds the aggregates together, and the mixture hardens into concrete.

Production. Lime is made from indigenous limestone or chalk rock, one of the most abundant materials in the Earth's crust. Limestone and chalk are both sedimentary rocks and are chemically known as calcium carbonate. When crushed or ground, they are widely used as aggregates and building products. As a raw material, calcium carbonate can …

Yes, limestone is commonly used in making Portland cement, the most widely used type of cement. It is heated in a rotary kiln and combines with powdered clay to produce a product called clinker, which is then ground with a source of sulfate, like gypsum. This mixture is then mixed with water, sand, and crushed rock to create concrete.
