The major raw materials used in the manufacture of cement are Calcium, Silicon, Iron and Aluminum. The cement industry is a natural producer of CO2: 60% of emissions are due to the transformation of raw materials at high temperatures (the "decarbonation" of limestone), 40% result from the combustion required to heat the cement … Besides being the Editor in Chief, he also mentors team at GharPedia. Common materials used to manufacture cement include limestone, shells, and chalk or marl combined with shale, clay, slate, blast furnace slag, silica sand, and iron ore. Calcareous materials contain limestone or chalk while argillaceous materials comprise an oxide of silica-alumina and iron. This makes the cement sound if present in small quantity but an excess can make the cement unsound. results in shutdown. This plays a major role in imparting strength to concrete. aggregates contain opal which reacts with the alkalis of cement and thereby result in expansion phenomena. and varies from 720 - 1500 kcal / kg clinker produced. I am very thankful to Mr. Subrata Bhaumik, For example following may be used for Raw materials used for manufacturing of Portland cement are found naturally in the earth’s crust. with main clinker 0.659 % by wt. The quarry (where the mining activity is performed) is located 0.7 km away from the plant and has the main raw materials such as Limestone and shale, the other raw materials (Iron ore, silica sand, gypsum and pozzolana are brought from nearby places. A raw mill is an equipment used to grind raw materials into “Raw Mix” during the manufacture of cement. Limestone is the main raw material. Excess silica adds strength to cement but it prolongs the setting time. Obtain the required environmental licenses, for which you will most likely require an environmental impact study.

The raw materials needed to produce cement (calcium carbonate, silica, alumina and iron ore) are generally extracted from limestone rock, chalk, clayey schist or clay. If they are in excess in cement, they cause a number of troubles such as alkali-aggregate reaction, efflorescence and staining when used in concrete, the brickwork of masonry mortar. Step 1: extraction of raw materials. Raw materials used for manufacturing of Portland cement are found naturally in the earth’s crust. Therefore, it is necessary to select a amounts. The utilities for the cement manufacturing process are: Do you have any suggestions? These are generally distinguished as argillaceous components. Thus, lime can drastically change the properties of cement. Gypsum or hydrated cal. Therefore part of the kiln gases need to be bypassed. Cement - Cement - Extraction and processing: Raw materials employed in the manufacture of cement are extracted by quarrying in the case of hard rocks such as limestones, slates, and some shales, with the aid of blasting when necessary. The location of a cement plant depends mostly on the limestone deposits. 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. Deficiency of lime causes decreased strength and the cement sets quickly. They are produced by properly blending two or more types of cementitious materials and cement raw materials. Thus, the chemical components of cement are calcium (Ca), silicon (Si), aluminum (Al) and iron (Fe). Principal Calcareous materials contain limestone or chalk while argillaceous materials comprise an oxide of silica-alumina and iron. ; Raw material preparation: use cement mill to process materials into required sizes for cement clinker production. etc. materials for the production of cement.
