Cement Clinker an overview | ScienceDirect Topics
The incorporation of SSA into the manufacturing process has been found to significantly increase the P 2 O 5 and SO 3 contents in the resultant cement clinker. At the higher end of the tested SSA levels, these oxide contents become excessively high and this generally appears to suppress the formation of C 3 S, which is the mineral phase primarily responsible for setting behaviour and early

The basic, eggcup shaped lime kiln was provided with a conical or beehive shaped extension to increase draught and thus obtain the higher temperature needed to make cement clinker. For nearly half a century, this design, and minor modifications, remained the only method of manufacture. The kiln was restricted in size by the strength of the chunks of rawmix: if the charge in the kiln collapsed
