To develop a durability plan for a girder bridge with a design life of 100 years?
Mandatory concrete specifications for your project:
Minimum 28 days characteristic compressive strength is 50 MPa of all structural members.
Only GGBFS is available for this project as Supplementary Cementitious Material.
In general, to reduce the concrete embodied carbon, always use the maximum allowed GGBFS content in the binder composition in accordance with AS5100.5 specifications. However, due to some limitations in GGBFS supply for this project, the maximum GGBFS content allowed is 50%.
