Portland cement is the basic ingredient of concrete. Concrete is formed when portland cement creates a paste with water that binds with sand and rock to is manufactured through a closely controlled chemical combination of calcium, silicon, aluminum, iron and other ingredients.
Cement Production Dark Blue: Pantone 289 Light Blue: Pantone 646 Summary Safety Cement is classifi ed as an irritant. It contains complex compounds of calcium combined with silica, alumina and iron as well as small amounts of calcium sulfate, lime, various alkalis and chlorides and trace amounts of chromium compounds. When cement is mixed with water
Three main stages in the cement production process exist: x Raw limestone processing, raw material mixing and milling; x Clinker production (as intermediary byproduct) from raw limestone calcinations in a melting rotary kiln; x Clinker mixing and milling with .

produce only cement and 2 produce only clinker [1]. Cement Production – The manufacture of cement is a twostep process, notably, clinker production and cement grinding. In the first step, the raw materials are fed to the kiln system to produce clinker. Clinker consists of silicates, aluminates and ferrites of calcium
In dry and semi dry processes for manufacturing of cement, the raw materials are crushed and fed in the correct proportions into a grinding mill. The raw materials are dried and reduced in size to a fine powder in to grinding mill. The dry powder is called the raw .

Cement history. The Egyptians used calcined gypsum as a cement and the Greeks and Romans used lime made by heating limestone and added sand to make mortar, with coarser stones for concrete. The Romans found that a cement could be made which set under water and this was used for the construction of harbours.
THE CEMENT MANUFACTURING PROCESS Prof. Dr Elshafie Ahmed Gad Faculty of Applied Science Chemistry Dept. Portland Cement Portland cement is made by mixing substances containing CaCO3 with substances containing SiO2, Al2O3, Fe2O3 and heating them to a clinker which is subsequently ground to powder and mixed with 26 % gypsum Raw Materials Necessary for Portland Cement .

Cement is so fine that 1 pound of cement contains 150 billion grains. The cement is now ready for transport to readymix concrete companies to be used in a variety of construction projects. Although the dry process is the most modern and popular way to manufacture cement, some kilns in the United States use a wet process.
Portland cement manufacturing plants are part of hydraulic cement manufacturing, which also includes natural, masonry, and pozzolanic cement. The sixdigit Source Classification Code (SCC) for portland cement plants with wet process kilns is 305006, and the sixdigit SCC for plants with dry process kilns is 305007. Portland cement accounts for 95 percent of the hydraulic cement production in the .
The LCI of portland cement is the basis of the LCI of concrete, concrete products, and concrete structures. These LCIs are used in turn to conduct life cycle. assessments of concrete structures and other structures containing concrete.
The production of cement is either through the wet or dry process with the dry process as the preferred option because of the lower energy intensity. Cement production accounts for about 5% of total anthropogenic emissions (IFC, 2017). Cementbased structures constitute the largest surface area of all manmade structures (Odigure, 2009).
