L'emploi d'additions minérales en cobroyage avec le clinker peut permettre d'améliorer les performances des bétons de sable et de réduire la quantité consommée de ciment.
Abstract. This paper aims to review the progress in cement clinker chemistry since the last International Conference on the Chemistry of Cement in 2011. Although Portland cement clinker is still, by far, the most important compound of modern cements we show that there is a strong development of alternatives. This is mainly due to the …

Clinker residence time in the cooler can be determined on a theoretical basis when certain factors are known. For the purpose of illustration, three different cooler operating conditions will now be considered to determine the effects of changes of these critical variables. ... The reader may be familiar with the Blaine cement surface-testing ...
Clinker. Clinker is the backbone of cement production. It is essentially a mix of limestone and minerals that have been heated in a kiln and have been transformed by this heat. When limestone is converted to clinker, …

Le broyage du clinker dans des tubes-broyeurs à boulets en acier est une étape très consommatrice d'énergie électrique dans la fabrication du ciment, et son rendement …
From 5 to 8% of global CO2 emissions correspond to the cement industry [12–14] due to the calcination of limestone and the combustion of fossil fuels. Additionally, a large electricity supply is required for the limestone-, clinker-, and cement-crushing processes. Cement production consumes 7% of the global industrial energy [15]. …
Points forts. Démarrage progressif grâce au faible courant de démarrage. Élimination des contraintes mécaniques au démarrage. Réduction des coûts de maintenance. Optimisation de la vitesse du broyeur. Réduction de l'usure du broyeur. Amélioration de l'efficacité énergétique. Réduction de la consommation d'énergie réactive.
Despite the increasing tendency to use substitute materials (fly ash, and blast furnace slags, pozzolans or volcanic ash, etc.), clinker is still today the most used material for producing cement.
Clinker – MIT Concrete Sustainability Hub. Clinker, the residue formed by high-temperature burning of coal or similar materials, plays an important role in the composition of cement and contributes to the properties of cement in different ways. Our research provides a fundamental understanding of the relationship between the surface energy of ...

To avoid spillage from the inlet, the cooler is inclined 2.5° and given a speed of rotation of 3 rpm. The power consumption for the drive is about 3.5 kWh/ton. The clinker …
Tout au long de la cuisson, un ensemble de réactions physico-chimiques conduit à l'obtention du clinker. Pour obtenir un ciment aux propriétés hydrauliques actives, le clinker doit être à son tour broyé très finement. Ce broyage s'effectue dans des broyeurs à boulets (grand cylindre métallique
This chapter has assessed the use of MIBA as both an aggregate component and, after grinding, a cement component, in a range of concrete-related applications, including …
Abstract. Technological developments in over a century of production of Portland cement clinker have greatly improved the homogeneity of the feed and clinker leading to much more favourable conditions for alite formation which remains the key chemical reaction in the process. This development is described along with the thermodynamic processes ...

The main goal of the clinkering process is to produce the material of designed phase composition, which is called Portland cement clinker. Under the action of high …
Mineral additions can be mixed with the clinker before the grinding process. Thus, one obtains a 'coground' binder which can allow some reduction in the cement ratio. Some dune sand is added, in variable proportions, to the clinker, such as to obtain a coground binder from which different sandcrete mixes are defined. To distinguish the effects of the …
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 …
Le ciment Portland Artificiel (CPA) Composition : résulte du broyage du clinker et du sulfate de calcium (gypse ou anhydrite) pour régulariser la prise, et éventuellement de fillers en faible quantité (<3%). La teneur en clinker est au minimum 97%. Les résistances sont mesurées sur mortier normal à 2, 7 et 28 jours.

Portland cement clinker is composed of four principal phases: alite, which is close to tricalcium orthosilicate Ca 3 [SiO 4]O, belite close to dicalcium orthosilicate Ca 2 [SiO 4], tricalcium aluminate Ca 3 [Al 2 O 6] and ferrite C 2 (A, F). Chemical composition of these phases is complicated by solid solutions, which have the decisive ...
