How is concrete made from limestone? Shelly Company

Jan 29, 2014To 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.

Portland-Limestone Cement

Producers know that replacing some of the clinker in portland cement with ground limestone offers benefits, the most important being that it reduces the embodied CO2 of the cement. Modifying a concrete mix design to replace higher carbon materials with lower carbon ingredients is an effective strategy to reduce its environmental footprint.

Portland Limestone Cement: Seven Frequently Asked Questions

Feb 08, 2022Blending limestone in the cement allows for a reduction in the amount of clinker, which reduces the carbon footprint per ton of cement. In addition to PLCs, the concrete industry is dedicated to develop new technologies that contribute to a greater reduction in overall CO2 emissions. Is This Just Diluting the Cement?

How Cement Is Made

The most common way to manufacture portland cement is through a dry method. The first step is to quarry the principal raw materials, mainly limestone, clay, and other materials. After quarrying the rock is crushed. This involves several stages. The first crushing reduces the rock to a maximum size of about 6 inches.
