Concrete Innovation for Recycled Content and Low Environmental impact

Project description

Recycled aggregate concrete for low environmental impact

Concrete is made up of cement, water and aggregates, which account for up to 70 % of its volume. Using recycled aggregates can help recycle energy and reduce waste. However, despite research proving its feasibility, its utilisation in concrete production remains low. With the support of the Marie Skłodowska-Curie Actions programme, the CIRCLE project will create an international network dedicated to upscaling recycled aggregate concrete (RAC). It will improve knowledge of bio-based self-healing and carbonation of RAC, enhancing high-performance RAC, optimising the quality of recycled aggregates and assessing RAC applications through life cycle assessment. It will evaluate the environmental, economic and social benefits of RAC, promoting sustainability and a circular economy.

Objective

Concrete is the world’s second most-used material in construction, after water. It comprises three main ingredients: cement, water and aggregates. The latter constitute 60-70% of concrete’s total volume, representing a heavy environmental burden. Presently, the use of recycled aggregates (RA) in concrete production (reusing their embodied energy and decreasing waste dumping) is still marginal, even though its feasibility has been demonstrated at the research level. The overarching goal of the CIRCLE project is to form an international network of 10 organisations working to tackle the challenges in upscaling recycled aggregate concrete (RAC). The CIRCLE team includes interdisciplinary researchers renowned in this area, which will integrate their expertise towards the project’s overarching goal, following a carefully planned flowchart of activities: enhancing existing knowledge on bio-based self-healing and carbonation of RAC; fostering high-performance RAC; optimizing the quality of RA and RAC, and evaluating the potential of RAC through multi-criteria life cycle assessment; and assessing RAC in full-scale real applications. The intercontinental 342 PM planned in secondments within CIRCLE will be the vehicle for joint research, training and networking, which will benefit the institutions’ staff at all levels of seniority, as well as PhD students. CIRCLE spans European and Asian countries with a massive need for concrete infrastructure development. Given the overwhelming dominance of concrete worldwide as a structural material, the potential environmental, economic and social positive impacts of upscaling RAC are priceless. This has been perceived by authorities and stakeholders and there are ongoing initial efforts in some of the consortium countries to regulate this possibility, which makes CIRCLE very timely in terms of guidelines contribution. Promoting RAC through CIRCLE will foster sustainability and a circular economy, aligned with European and UN policies.
