Concrete With Limestone Calcined Clay Cement Concrete
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.

Geochemical assessment of a siliceous limestone
htm. For manufacturing of one ton of cement, a quantity of 1.5 ton of limestone is required. Hence, cement plants are necessarily located close to the limestone mines to minimize the transportation cost. The cement grade limestone deposits are depleting day by day because of continuous exploitation of high grade limestone over the years.
Are You Mining Minerals for Cement or for Concrete
You might think of a cement manufacturing facility as an extension to a mining operation, as cement plants are typically located central to the minerals required to make the cement, which saves the transportation costs and reduces the price of the cement. Limestone is one of the key minerals used in cement making. Limestone is a sedimentary ...

Cement manufacturing components of a cement plant
Cement is typically made from limestone and clay or shale. These raw materials are extracted from the quarry crushed to a very fine powder and then blended in the correct proportions. This blended raw material is called the raw feed or kiln feed and is heated in a rotary kiln where it reaches a temperature of about 1400 C to 1500 C.
