Abstract
Global warming caused due to CO2 emissions is increasing at an alarming rate. Cement production is known to contribute ∼7% of global CO2 emissions. Efforts are being made to minimize the emission of CO2 per tonne of clinker from the present rate of 0.86 t/t clinker to 0.35 t/t by 2050. Many steps are being taken to achieve the above mentioned target. Around 60% of the total CO2 emitted during cement manufacture is due to calcination process. Thus it is evident that use of a non carbonate lime bearing raw material for cement manufacture can drastically reduce the CO2 emission. In this paper we have systematically studied of wollastonite minerals were used in different ratio. Mix designs were prepared using 1–5% wollastonite by replacing limestone content in the raw mix. A control sample was also designed without using wollastonite mineral. The results of the mineralogical analysis showed that the clinker phases with wollastonite at 1400 °C were comparable to the control clinker at 1450 °C.
