Project Title: Evidence and Demonstration for the Adoption of New Low Carbon Cement Technologies in the Irish Market
Lead RPO: UCD
Lead PI: Ciaran McNally, Dan McCrum, Mehran Khan
Industry Partners: Ecocem, Cairn Homes, Kilsaran
Collaborators: Egis, Kwick RC Frames
Abstract: The Irish construction sector urgently needs to address the intertwined, and unfortunately conflicting, challenges of increasing the delivery of housing, while also reducing the environmental impact of a carbon-intensive construction industry.
Cairn Homes has committed to reducing their Scope 3 emissions intensity by 61% from a 2019 baseline, by 2030. To achieve that goal, solutions for embodied carbon in cement are needed through development, scaling, testing and certification of Supplementary Cementitious Materials (SCMs), such as Ecocem’s ACT. ACT is a next generation low-carbon cement technology which can deliver a globally scalable 70% reduction in the cement industry’s carbon footprint and Ecocem is preparing to deploy it in Ireland. The project intends to build on the strong R&D already undertaken by Ecocem across Europe, and will involve:
· Construction of a full-scale “Irish Demonstrator” using ACT to validate the buildability of various mixes in different scenarios; and
· Undertaking extensive laboratory testing to assess the material and strength characteristics of concrete made using Ecocem ACT for certification/compliance, building on existing durability testing under way in UCD.
For the first time, the project evidence and a buildability demonstrator will enable standards authorities to update relevant codes to adopt alternative SCMs and binders in Ireland.
