Laying the foundation for a zero carbon cement industry

Laying the foundation for a zero carbon cement industry

May 14, 2020 Cement acts as the binder between aggregates (fine and coarse rocks) in the formation of concrete. While cement makes up only a small percentage of the mix (approximately 12 percent by volume), it is almost exclusively responsible for the resulting CO 2 emissions. In the cement-manufacturing process, raw materials are heated to high temperatures in a kiln in a fuel-intensive …

Recycling of Cement Kiln Dust as a Raw Material for Cement

Recycling of Cement Kiln Dust as a Raw Material for Cement

Cement kiln dust (CKD) is a major by-product of cement manufacturing and has the potential to be recycled as a raw material if the high concentrations of chlorine and potassium are removed. This study tested four leaching solutions (distilled water and three organic acids) and determined the optimum reaction conditions. At a liquid/solid (L/S ratio) of 10, the removal efficiency of formic ...

Cement Extraction and processing Britannica

In the semidry process the raw materials, in the form of nodules containing 10 to 15 percent water, are fed onto a traveling chain grate before passing to the shorter rotary kiln. Hot gases coming from the kiln are sucked through the raw nodules on the grate, preheating the nodules. Dust emission from cement kilns can be a serious nuisance.
