The term "cement" is most often used to refer toPortland cement.Portland cement, when mixed with sand, gravel, and water, makes concrete, which is an essential element of the construction industry.Portland cementaccounts for more than 95% of all cement produced. To makePortland cement, clay, shale and limestone is ground to a powder and baked in a kiln.
Portland cement, binding material in the form of a finely ground powder, usually gray, that is manufactured by burning and grinding a mixture of limestone and clay or limestone and shale. The inventor Joseph Aspdin, of England, patented the basic process in 1824, naming it for the resemblance of the cement when set to portland stone, a limestone from the Isle of Portland .

On the other hand,portland cementis an artificial mixture of raw materials, has a calcination at a temperature above 2,000 degrees Fahrenheit, and purer raw materials were used than necessary for natural cements. The raw materials used in the manufacturing ofportland cementat this time werecementrock, limestone, shale, and coal.
Portland cementis the world’s most widely used manufactured material and underpins modern infrastructure like no other. Global production ofPortland cementclinker stands at a little over 3.5 billion tonnes, and consequently the globalcementindustry is responsible for 6–7% of anthropogenic carbon dioxide emissions.
Portland cementis the basic ingredient of concrete. Concrete is formed whenportland cementcreates 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.
