Simple Input Method (A1) - LOI of Raw Meal

2020-2-27  CO 2 emissions from the organic carbon content (TOC) of raw materials are partially included by using the LOI of raw meal as the principle parameter. However, a separate analysis and determination of CO 2 emissions from the TOC will be required for raw materials with high TOC content. This could be necessary, for example, if a plant consumes substantial volumes of shale or fly ash high in TOC content as raw materials

Raw Material Substitution - Cembureau

The main raw material used in cement production has traditionally been limestone. Limestone is abundantly available, but over 60% of the industry’s CO 2 emissions are caused by transformation of limestone into lime, called “decarbonation”. Accordingly, part of the route towards a low carbon concrete-built environment can involve limestone substitution.
