What is Cement Clinker? Composition, Types & Uses - Civil ...

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.

Portland cement clinker - Understanding Cement

Portland cement clinker - overview. Portland cement clinker is a dark grey nodular material made by heating ground limestone and clay at a temperature of about 1400 °C - 1500 °C. The nodules are ground up to a fine powder to produce cement, with a small amount of gypsum added to control the setting properties. This page gives a thumbnail sketch.

Cement Production | Cement | Howden

Once the raw materials have been crushed into raw meal, they are transported to the kiln and Howden fans play an important role in super heating the meal into the cement clinker and then to cool the clinker. The clinker then has gypsum added and is moved into the cement mill to be ground into the final product.

Clinker (cement) - Wikipedia

In the manufacture of Portland cement, clinker occurs as lumps or nodules, usually 3 millimetres to 25 millimetres in diameter, produced by sintering limestone and aluminosilicate materials such as clay during the cement kiln stage.

The Importance of Cement and its Future | Cement Science

The Importance of Cement and its Future. Concrete is the most used material in the world because of its cheap price and large quantity. It is needless to say concrete is made of cement. However, cement is also a criticized material by the public, for its intensive CO 2 emission from production process. The production of cement accounts for about 5-8% of the non-natural CO 2 worldwide.

Why is cement important to construction? - Quora

Concrete is made using cement, sand, gelly. Concrete plays an important role in any kind of construction. Concrete gives strength to any structure and it it hardens up over a period of time. And cement acts as a binding agent in concrete. A good quality cement has other adhesives Silica (SiO2) and Alumina (Al2O3).

Cement and clinker trade and risk of a Chinese slowdown

Sep 30, 2016 · The ability to sell cement (or clinker) in long distance markets not only brings the profits that go with the trade itself, but ensures a substantial reduction in production costs per tonne over the full production volume of the plant. Approximately 800-900Mt/yr of clinker and cement benefit from seaborne cement and clinker trade and distribution.

Clinker Substitution - Cembureau

Cement standards serve to guarantee the performance of each cement type. The use of other constituents has an impact on the way the cement will perform in both the short and long term. The success of cements with a low clinker-to-cement ratio will also depend on market acceptance.

Cement - Wikipedia

Conversely, hydraulic cement hardens by hydration of the clinker minerals when water is added. Hydraulic cements (such as Portland cement) are made of a mixture of silicates and oxides, the four main mineral phases of the clinker, abbreviated in the cement chemist notation, being: C 3 S: Alite (3CaO·SiO 2); C 2 S: Belite (2CaO·SiO 2);

Cement - International Energy Agency

May 29, 2019 · From 2014 to 2016, the direct CO 2 intensity of cement showed little change, as thermal energy efficiency improvements were offset by a slight increase in the global clinker-to-cement ratio. To meet the IEA SDS objectives, the direct CO 2 intensity of cement needs to decline by 0.3% annually through to 2030, even as cement production is expected to grow.
