— Upon calcination the calcite CaCO 3 peaks almost totally disappeared in the calcined limestone sample due to its decomposition to form lime CaO whose peaks became more apparent This indicated that the calcination procedure with the target temperature of 950 °C effectively decomposed most of the calcite in the raw material

— This paper reports a comprehensive literature review on the carbonation potential of lime in different applications The total carbonation potential is assessed as carbonation rate the ratio between the CO 2 reabsorbed through carbonation during the operational life of lime and the CO 2 emitted during limestone calcination
— Apart from the assessment of the environmental impacts of current cement production practices which is a rather underexplored topic in Myanmar an original aspect of the study is the modelling of two scenarios emphasizing fuel use during the calcination process to identify possible mitigation options Section
