Cement Raw Materials used in Manufacturing of Cement

Raw materials used for manufacturing of Portland cement are found naturally in the earth’s crust. It is made primarily from calcareous and argillaceous materials and gypsum. Calcareous materials contain limestone or chalk while argillaceous materials comprise an oxide of silica-alumina and iron. Both are found as clay or shale. Let’s understand the various types of cement raw materials ...

Power plant ashes as substitute raw materials - Global

19/11/2012  Use as alternative raw material in cement production. Clinker: Fly ash from coal-fired power plants can be used effectively as a component of raw kiln feed for the manufacture of cement clinker. Fly ash contains significant amounts of Al 2 O 3 and SiO 2 and has thus been used as a partial replacement of natural raw materials like clay and/or shale in the raw kiln feed. In some cases the Fe

ALTERNATIVE RAW MATERIAL SOURCES FOR CEMENT

To mine the chief raw material for the manufacture of cement- limestone requires a lot of machines, plants and explosives. A lot of money is also paid as compensation to the communities that own the land. All these expenditures lead to the high cost of cement. This study was therefore to investigate alternative source of raw material for the production of cement.

Cement - Extraction and processing Britannica

A first approximation of the chemical composition required for a particular cement is obtained by selective quarrying and control of the raw material fed to the crushing and grinding plant. Finer control is obtained by drawing material from two or more batches containing raw mixes of slightly different composition. In the dry process these mixes are stored in silos; slurry tanks are used in ...

The raw materials and mixes shown are only "typical": considerable variations are possible depending on the raw materials available. Control of minor elements. Apart from the major oxides (CaO, SiO 2, Al 2 O 3 and Fe 2 O 3) the minor oxides are, at best, diluents of the clinker, and may be deleterious.However, cement raw materials are for the most part dug from the Earth's crust and contain ...

Fly Ash as a Portland Cement Raw Material

In 1966, approximately 125 million tons of raw materials, exclusive of fuel, air, water, and power were consumed to produce almost 74 million tons of portland cement in the United States that is about 3,400 pounds of raw material per ton of finished cement produced. To present the figure in another way, a single plant producing 600,000 tons of cement a year would consume about 1,000,000 tons ...
