What is cement made of? For the bulk and continuous manufacturing and production of Portland Cement following mineral materials are used: calcareous materials (limestone or chalk), argillaceous material (shale or clay), blast furnace slag, silica sand, iron ore, and gypsum as raw material. Cement factories are established where these raw materials …
Cement primarily consists of lime (calcium oxide, CaO), silica (silicon dioxide, SiO2) and alumina (aluminium oxide, Al2O3). The lime comes from a calcareous raw material, whereas the other oxides come from an argillaceous or clayey source.
Raw Materials Used in the Manufacturing of Cement. The preparation of cement using the raw materials involves the following process: Step 1: Mining-The extraction of raw materials such as limestone and clay from mines and quarries. Step 2: Grinding process-These raw materials are grinded and crushed into a fine powder-like form. This is called ...

Materials used to produce portland cement. Q. What are the raw materials used in the manufacture of portland cement? A. The two principal materials from which portland cement is made are a material of high lime content, such as limestone, chalk, shells, or marl, and a material of high silica and alumina content such as clay, shale, or blast-furnace slag. A small …
How Concrete is Made: Water. This is the mix's vital fluid, which sets of a chemical reaction when it comes into contact with the cement. How Concrete is Made: Cement. No other material rivals cement's importance in the mix; it's the ingredient that gives concrete its resistance. How Concrete is Made: Concrete mixing
11.6 Portland Cement Manufacturing 11.6.1 Process Description1-7 Portland cement is a fine powder, gray or white in color, that consists of a mixture of hydraulic cement materials comprising primarily calcium silicates, aluminates and aluminoferrites. More than 30 raw materials are known to be used in the manufacture of portland cement, and these
The major raw materials used as a source of CaO for cement manufacturing are limestone, chalk, marl, etc. These raw materials by virtue of their natural occurrence contains other mineral impurities e.g, MgO, SiO 2, Al 2 O 3, Fe 2 O 3, alkali compounds, and sulfides.These impurities play an important role to influence the cement manufacturing …
Cement - Composition, Properties, Major Cements: Portland cement is made up of four main compounds: tricalcium silicate (3CaO · SiO2), dicalcium silicate (2CaO · SiO2), tricalcium aluminate (3CaO · Al2O3), and a tetra-calcium aluminoferrite (4CaO · Al2O3Fe2O3).
