Modelling the cement process and cement clinker quality

Mar 08 2012 The properties of clinker which are closely related with the burning condition such as grindability of clinker and strength of cement can be estimated from the microscopically characters The temperature curve of clinkerburning can be drawn approximately from the four terms namely burning rate maximum temperature keeping time and cool rate Half of cement process CO2 emissions are due to the chemical reaction in cement clinker production These process emissions are not affected by energy efficiency measures Yet it might be possible to reduce clinker production by 300 Mt with more extensive use of clinker substitutes which could reduce CO2 emissions by about 240 Mt CO2 per year
