Concrete PAV2 with 14% limestone cement

Emission intensity of concrete PAV2 with 14% limestone cement. Assumed 356 kg total cementitious content per m3 concrete. Estimated from ICE Cement Mortar Concrete model with an estimate of realistic cement contents not minimum cement contents. More cement is often added into a mixture e.g. to cure quicker. Concrete has a wide variation of cement contents for the same strength class of concrete. This adds additional uncertainty to this data by strength class. There is no substitute for finding out the actual cement content used in a mixture (not specified min cement content - actual cement content used by the contractor). The cement content for your mixture at this strength class might be a very different value than assumed here. The source does not clarify if the kgCO2e value is calculated using either IPCC Fourth Assessment Report (AR4) or IPCC Fifth Assessment Report (AR5) methodologies.
