Embodied Carbon Model for Concrete
This carbon calculator can be used to calculate the embodied carbon of concrete mixtures. Boundaries are cradle to gate plus the option of transport to site.
1. Concrete Mixture

Cement replacement materials, such as GGBS and fly ash, can be selected by:

  1. Selecting a cement type with the correct blend in section 1b; and by
  2. Adding additional cement replacement material in section 1c.

Do NOT double count the cement replacement materials

1a. Mixture Name
Long names may not display well on the result graphs.
Enter mix Name
Mix 1
Mix 2
Mix 3
1b. Select cement type
If you want to model cement types not covered by the built in list, then enter a CEM I and model the correct blend of cement replacements in section 1d
SELECT cement type
If you selected custom cement data in the drop down above, you will need to complete this section. Otherwise, move to the next section.
Enter EPD result, GWP – Mod A1-3, kg CO2e per kg cement
1c. Enter quantity of above cement type
Cement, kg per m3
1d. Enter any additional cement replacements
Do not double count if already included in the cement type selected in 1b (e.g. additional material not covered by the cement type selected in section 1b)
