ECOS brief – A performance-based standard for common cements
Cement – and concrete – are indispensable in our modern day lives. However, the production of traditional cement, better known as Portland cement (PC), is responsible for 8% of global CO2 emissions. Given that cement makes up for over 90% of CO2 emissions at concrete level, substantial GHG emissions reductions for concrete will require eco-innovation at the cement level.
To develop performance-based standards that enable material innovation and rapid decarbonisation of the cement and concrete value chain, three elements are essential:
- Performance and impact parameters: properties that relate to desired performance or impact (strength, durability, environmental footprint…)
- Adapted quality criteria with regards to the desired use and impact.
- Good performance-based methods that can predict long-term behavior (e.g. chloride, carbonation) with clear, reliable, and easy-to-use testing and calculation methods.
