Concrete With Limestone Calcined Clay Cement

Cement is normally made from Limestone, Silica, Alumina and Gypsum, but when all these ingredients are mixed at a temperature of 1500o C, it causes an emission of CO2 on environment. To reduce this, the researchers found that the use of clinker should be reduced. And here the answer is Limestone Calcined clay cement.

How is concrete made from limestone? Shelly

2014-1-29  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.

How Cement Is Made

After the clinker is cooled, cement plants grind it and mix it with small amounts of gypsum and limestone. Cement is so fine that 1 pound of cement contains 150 billion grains. The cement is now ready for transport to ready-mix concrete companies to be used in a variety of construction projects.
