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.

Explained: Cement vs. concrete — their differences, and
What makes concrete so strong is the chemical reaction that occurs when cement and water mix — a process known as hydration. “Hydration occurs when cement and water react,” says Ulm. “During hydration, the clinker dissolves into the calcium and recombines with water and silica to form calcium silica hydrates.”

How Cement Is Made
These ingredients, when heated at high temperatures form a rock-like substance that is ground into the fine powder that we commonly think of as cement. Bricklayer Joseph Aspdin of Leeds, England first made portland cement early in the 19th century by burning powdered limestone and clay in his kitchen stove.

Understanding Limestone in Cement
The limestone acts as a seed crystal for the cement, better distributing the reaction products and increasing the reactivity of the cement. As there is always unhydrated cement in the concrete, this change will have no real measurable effect on the use of fly ash. The cement might have a reduced water demand, and the coarser cement gradation

The concrete industry therefore is enormous, and this comes at a cost: It is estimated that around 7% of the world’s carbon dioxide emissions come from the manufacture and use of cement, the main component of concrete. And a large proportion of this 7% is due to the necessary use of calcium, which is usually obtained by burning limestone.

Making Limestone Into Cement
While the process of making cement uses a number of tools, the production of concrete requires only a concrete mixer. In the first stage of making cement, limestone and clay are crushed together to form a powder. This powder is then combined in a mixer before passing into a rotating heater which has constant heat applied at one end of the tube.

Because the limestone is softer than the clinker it will grind preferentially, resulting in a cement with a better particle size distribution with less energy. The limestone also requires less processing and does not undergo calcination, so it releases less waste in its production. The resulting cement will perform at least as well as cements

Magnesium Oxide in Portland Cement
As limestone constitutes about 77% of the raw meal by weight, the major contribution of MgO comes from magnesium carbonate present in it. At the clinkering temperature of about 1450°C at which the raw meal is generally burnt to produce cement clinker, magnesia gets dead-burnt. The dead-burnt magnesia, called periclase, hydrates slowly in water at ambient temperatures. Its hydration in cement

It is then preheated to save energy before being transferred to the kiln, the heart of the process. The kiln is then heated to a high temperature of up to 1480 degrees to convert the material to a molten form called clinker. The clinker is then cooled and ground to a fine
