cement process and raw material detail

Raw materials employed in the manufacture of cement are extracted by quarrying in the case ofhard rockssuch aslimestones,slates, and someshales, with the aid of blasting when necessary. Some deposits are mined by underground methods.Softer rockssuch aschalk…

Concreteis formed when portlandcementcreates a paste with water that binds with sand and rock to harden.Cementis manufactured through a closely controlled chemical combination of calcium, silicon, aluminum, iron and other ingredients. Commonmaterialsused to manufacturecement…

Raw Materials of Cement. Most important raw materials (what is cement made of) required in the manufacture of Portland Cement are: Limestone, Clay, Gypsum,Fuel, and Water (in wet method). These are sedimentary,calcium carbonate rocks(CaC0 3 ). Most commonly they contain a small amount ofmagnesium carbonatealso.

Aug 30, 2012·Cement Manufacturing Process Phase1:Raw Material Extraction. Cement uses raw materials that cover calcium, silicon, iron and aluminum. Such raw materials are limestone, clay and sand. Limestone is for calcium. It is combined with much smaller proportions of sand and clay. Sand & clay fulfill the need of silicon, iron and aluminum.

Manufacturing ofcementinvolves variousraw materialsandprocesses. Eachprocessis explained chemical reactions for manufacture ofPortland Cement.Cementis a greenishgrey colored powder, made of calcined mixtures of clay and limestone. When mixed with water becomes a hard and strongbuilding material.

Cement-Cement-Extraction and processing:Raw materialsemployed in the manufacture ofcementare extracted by quarrying in the case of hard rocks such as limestones, slates, and some shales, with the aid of blasting when necessary. Some deposits are mined by underground methods. Softer rocks such as chalk and clay can be dug directly by excavators.

15 Types ofCement-Details& Uses in Construction.Cementis a bindingmaterialwhich makes a bond between aggregates and reinforcingmaterialstogether. With the development of technology, quality and types ofcementhave also developed. So there are different types ofcementfor different construction works. Types ofCement

Cementis so fine that 1 pound ofcementcontains 150 billion grains. Thecementis now ready for transport to ready-mixconcretecompanies to be used in a variety of construction projects. Although the dryprocessis the most modern and popular way to manufacturecement, some kilns in the United States use a wetprocess.

Cementis typically made from limestone and clay or shale. Theseraw materialsare extracted from the quarry crushed to a very fine powder and then blended in the correct proportions. This blendedraw materialis called the 'rawfeed' or 'kiln feed' and is heated in a rotary kiln where it reaches a temperature of about 1400 C to 1500 C.

Portland cementcan be made by following two different processes – a dry one and a wet one. Joseph Aspdin first madeportland cementin his kitchen stove in England in the 19th century. Lime and silica make up approximately 85% ofportland cement. Thematerialsthat are commonly used are limestone, shells, chalk, shale, clay, slate, silica sand, and iron ore.

Concreteis a hardened buildingmaterialcreated by combining a chemically inert mineral aggregate (usually sand, gravel, or crushed stone), a binder (natural or syntheticcement), chemical additives, and water.
