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 …

Research status of super sulfate cement
The finer the cement, the higher the specific surface area. The increase of fineness will promote the hydration of SSC (Liu and Li, 2014).Consequently, the finer SCC has a higher hydration rate and more total hydration heat released (Liu and Li, 2014; Liu et al., 2015).As shown in Fig. 2, the increase of the specific surface area accelerates the …
