Portland cement - Wikipedia
Portland cement is the most common type of cement in general use around the world as a basic ingredient of concrete, mortar, stucco, and non-specialty grout. It was developed from other types of hydraulic lime in England in the early 19th century by Joseph Aspdin, and usually originates from limestone.

Portland Cement - an overview | ScienceDirect Topics
Production of Cement. Portland cement is a complex mixture of compounds formed from the oxides of calcium (CaO), silicon (SiO 2), aluminium (Al 2 O 3), and iron (Fe 2 O 3). In addition to these four main constituents, it also contains smaller amounts of magnesium oxide (MgO) and oxides of the alkali metals potassium (K 2 O) and sodium (Na 2 O). It is produced by heating together naturally …

Cement clinker - Wikipedia
Cement clinker is a solid material produced in the manufacture of Portland cement as an intermediary product. Clinker occurs as lumps or nodules, usually 3 millimetres (0.12 in) to 25 millimetres (0.98 in) in diameter. It is produced by sintering (fusing together without melting to the point of liquefaction) limestone and aluminosilicate materials such as clay during the cement kiln stage.
Lime vs Portland cement? Which is better? — Stonehenge ...
Portland cement is about 30% clay-based, while lime is usually about 5% clay. However, there are three basic strengths of lime mortar, depending on the amount of clay present. The closer the clay percentage gets to 30%, the closer it is to a Portland cement, since the strength will be the same.

Aug 30, 2012 · Cement is the basic ingredient of construction and the most widely used construction material. It is a very critical ingredient, because only cement has the ability of enhancing viscosity of concrete which in returns provides the better locking of sand and gravels together in a concrete mix.
How Portland Cement is Made? Manufacturing Process of ...
By mass, lime and silica make up approximately 85% of portland cement. The materials that are commonly used are limestone, shells, chalk, shale, clay, slate, silica sand, and iron ore. Since limestone is the main component, often cement plants are located near limestone quarries. The first step in both manufacturing processes after quarrying is primary crushing.
