Whereas, cement manufacturing as it is, is incompatible with the zero emissions requirement of the near future. Limestone is considered equivalent to coal by (Zero Carbon Industry Plan, 2017), as the thermal processing of limestone releases a similar amount of CO 2 as the combustion of coal for its thermal energy. Also, both …
In comparison with blended cement prepared with higher kaolinite calcined coal gangue or calcined clay (>40%) as reported in the literature [25], [37], [38], the later strength at the cement replacement level of 30% and 45% were found to be similar with that of control OPC sample. As for group 2 samples (without LS), the 7d and 28d …
