Cement Production an overview ScienceDirect Topics

The production of cement is either through the wet or dry process with the dry process as the preferred option because of the lower energy intensity. Cement production accounts for about 5% of total anthropogenic emissions (IFC, 2017). Cement-based structures constitute the largest surface area of all man-made structures (Odigure, 2009).

Manufacturing of Portland Cement Process and Materials

The manufacture of Portland cement is a complex process and done in the following steps: grinding the raw materials, mixing them in certain proportions depending upon their purity and composition, and burning them to sintering in a kiln at a temperature of about 1350 to 1500 ⁰C. During this process, these materials partially fuse to form nodular shaped clinker by broking of chemical bonds of

Full-Depth Reclamation a Cost-Effective, Durable Option

Life-cycle cost analysis showed that based on MnDOT standards, FDR is more cost- effective over a 35-year period than is mill and overlay. Because the analysis did not include road user costs associated with rehabilitation activities, the cost-effectiveness of FDR, already better than that for traditional pavement rehabilitation, is understated.
