Cement Production - an overview ScienceDirect Topics

One process that has not been extensively investigated is carbon sequestration. In this process, the hydrated cement reacts with CO 2 in the air, slowly reversing some of the processes that took place in the kiln when the cement was made (this is the carbonation process; it also causes reinforcement corrosion, see Section 25.3.2). It is estimated that this may reduce the carbon footprint of the cement industry by

Cement Production - an overview ScienceDirect Topics

G. Habert, in Eco-efficient Construction and Building Materials, 2014 10.1 Introduction. Cement production has undergone tremendous developments since its beginnings some 2,000 years ago. While the use of cement in concrete has a very long history (Malinowsky, 1991), the industrial production of cements started in the middle of the 19 th century, first with shaft kilns, which were later ...

The cement kiln

The dry process is much more thermally efficient than the wet process. Firstly, and most obviously, this is because the meal is a dry powder and there is little or no water that has to be evaporated. Secondly, and less obviously, the process of transferring heat is much more efficient in a dry process
