Limestone - Wikipedia

Limestone is commonly white to gray in color. Limestone that is unusually rich in organic matter can be almost black in color, while traces of iron or manganese can give limestone an off-white to yellow to red color. The density of limestone depends on its porosity, which varies from 0.1% for the densest limestone to 40% for chalk.

What is Calcium Carbonate Limestone? | Carmeuse

The transformation process consists of decarbonating limestone, which separates the CaO and CO 2. Next, these elements are recombined. The CaO and CO 2 are recombined through a process that takes place with the help of a chemical reactor. The final product has the same chemical composition as calcium carbonate.

How is concrete made from limestone? | Shelly Company

To make Portland cement—the most common type of cement—powdered limestone is heated in a rotary kiln. As a source of calcium, it joins with powdered clay to produce a product called clinker, which is then ground with a source of sulfate, like gypsum. It is mixed with water, sand and crushed rock to create concrete.

New approach suggests path to emissions-free cement

In the new process, the pulverized limestone is dissolved in the acid at one electrode and high-purity carbon dioxide is released, while calcium hydroxide, generally known as lime, precipitates out as a solid at the other. The calcium hydroxide can then be processed in another step to produce the cement, which is mostly calcium silicate.
