Clinker (waste) - Wikipedia

Clinker is a general name given to waste from industrial processes, particularly those that involve smelting metals, welding, burning fossil fuels and use of a blacksmith's forge, which commonly causes a large buildup of clinker around the tuyere. Clinker often forms a loose, dark deposit consisting of waste materials such as coke, coal, slag, charcoal, and grit. Clinker often has a Limestoney look to it, usually because of the formation of molten silicacompounds during processing. Clinker generally is much denser than co

Processing Clinker from Wastes: A New Raw

The first stage of work was the waste characterization. Then different blends were prepared and submitted to distinct firing cycles to obtain Portland clinker, the main component of the ordinary cement. Using only wastes in adjusted proportions and under tuned firing cycle, it was possible to obtain ecological Portland clinker. Moreover, it was possible to reduce, by about 50 °C, the clinkering temperature in relation to the value used

Laying the foundation for a zero-carbon cement

CO 2 emissions are directly proportionate to the amount of clinker used in cement production. Therefore, clinker can be substituted by cementitious materials such as natural and calcined pozzolans, as well as industrial byproducts such as fly ash and blast furnace slag. Similarly, the use of pozzolans depends on their availability, as natural reserves are limited to specific regions.
