Le béton est un matériau de construction composite fabriqué à partir de granulats naturels (sable, gravillons) ou artificiels (granulats légers) agglomérés par un liant.. Le liant peut être qualifié d'« hydrique », lorsque sa prise se fait par hydratation. Ce liant est appelé couramment « ciment » ; on obtient dans ce cas un « béton de ciment » un des plus …

Types of Clinker. The most common type of Clinker is produced for Portland cement and its blends. The types of Clinker vary depending on the type of cement for which the Clinker is produced. Aside from the Portland cement blends, some special types of cement clinker are listed below: Sulfate Resistant Clinker; Low Heat Clinker; White Clinker

Clinker is made by combining lime and silica and also lime with alumina and iron. If some of the lime remains uncombined, (which it almost certainly will) we need to subtract this from the total lime content before we do the calculation in order to get the best estimate of the proportions of the four main clinker minerals present. For this ...

The clinker SO3 content has been recognized as having an impact on grindability. Higher SO3 in clinker results in a reduction in grindability and increases specific power consumption per ton. Also, increasing SO3 (above optimum) content in clinker results in a decline of the 28 day cube strengths at a constant Blaine.

Clinker is a nodular material which is produced in the kilning stage during the production of cement. It is used as a binder in many cement products. Clinker nodules are around 3-25 mm in diameter and dark grey in colour. Limestone and clay is heated to about 1400oC-1500oC in the rotary kiln to produce clinker.
