The first step in making concrete is to prepare the cement. One type of cement, Pordand cement, is considered superior to natural cement because it is stronger, more durable, and of a more consistent quality. To make it, the raw materials are crushed and ground into a fine powder and mixed together.

This paper adds new knowledge on how raw materials should be managed in iron and steelmaking firms. While previous research has contributed significantly to how firms should deal with functional challenges related to raw materials, the understanding of Raw Materials Management from a holistic perspective is largely lacking, and extant research does not provide qualified advice to firms on this

Raw materials are extracted from the quarry, then crushed and ground as necessary to provide a fine material for blending. Most of the material is usually ground finer than 90 microns
Some typical materials used for iron in cement manufacturing are iron ores, blast furnace flue dusts, pyrite clinker, mill scale, and fly ash.” Cement manufacturers must process the selected and prepared mineral raw materials to produce the synthetic mineral mixture (clinker) that can be ground to a powder having the specific chemical composition and physical properties of cement.

Raw materials. For the production of steel, there is a need for iron raw material in the form of iron ore or scrap metal, together with alloying elements so that the material acquires the desired for properties. In the production of ore-based steel, coal is also needed as a reducing agent and limestone as a slag former.

Iron oxide: Chemical formula is Fe 2 O 3. Iron oxide imparts color to cement. It acts as a flux. At a very high temperature, it imparts into the chemical reaction with calcium and aluminum to form tricalcium alumino-ferrite. Tricalcium alumino-ferrite imparts hardness and strength to cement. Calcium Sulfate: Chemical formula is CaSO 4.

Also, super cheap casting material. You will be surprised at the detail you can get with concrete and cement. Cement is the limestone part of the concrete. Concrete has the agglomerates such as rock or gravel in it. The cement by itself won’t be as strong as the concrete, but you can mix it with sand or other particles to make a nice finish.

During this process, these materials partially fuse to form nodular shaped clinker by broking of chemical bonds of the raw materials and recombined into new compounds. The clinker is cooled and ground to a fine powder with the addition of about 3 to 5% of gypsum. By this process, the product formed is Portland cement.
