This journal is designed to reflect current developments and advances being made in the general field of cement-concrete composites technology and in the production, use, and performance of cement-based construction materials.The word cement is interpreted in a wide sense, including not only Portland cement but also blended cements and other binding materials.
Cement - The major cements: composition and …
18-5-2020 · Cement - Cement - The major cements: composition and properties: Portland cement is made up of four main compounds: tricalcium silicate (3CaO · SiO2), dicalcium silicate (2CaO · SiO2), tricalcium aluminate (3CaO · Al2O3), and a tetra-calcium aluminoferrite (4CaO · Al2O3Fe2O3). In an abbreviated notation differing from the normal atomic symbols, these compounds are designated as …
How Concrete is Made - Portland Cement …
The longer the concrete is kept moist, the stronger and more durable it will become. The rate of hardening depends upon the composition and fineness of the cement, the mix proportions, and the moisture and temperature conditions. Concrete continues to get stronger as it gets older.

John Bensted, in Leas Chemistry of Cement and Concrete (Fourth Edition), 1998. Ordinary hydration. Oilwell cements are usually based upon Portland cement compositions, which comprise four principal clinker mineral phases: tricalcium silicate (Ca 3 SiO 5), dicalcium silicate (Ca 2 SiO 4), tricalcium aluminate (Ca 3 Al 2 O 6) and a calcium aluminoferrite of more variable composition ...
What is Cement Clinker? Composition, Types & …
Clinker is a nodular material produced in the kilning stage during the production of cement and is used as the binder in many cement products. The lumps or nodules of clinker are usually of diameter 3-25 mm and dark grey in color. It is produced by heating limestone and clay to the point of liquefaction at about 1400°C-1500°C in the rotary kiln. ...

How Cement Is Made
Cement is so fine that 1 pound of cement contains 150 billion grains. The cement is now ready for transport to ready-mix 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.
