2026-06-02 11:00 2026-06-02 14:00 Europe/Madrid Design of concrete with low-carbon cements: the influence of aggregates
In the current context of decarbonization, concrete design cannot focus solely on cement. Aggregates, due to their nature, origin, grading and quality, play a decisive role in water demand, paste content, admixture dosage, mechanical performance and durability of concrete and, therefore, in its overall environmental footprint.
This session will address how to optimize the design of concrete with low-carbon cements by jointly considering cement, aggregates and admixtures, with a practical approach focused on material compatibility, production robustness and the final performance of concrete.
The session will bring together representatives from industry, sector associations and research centers to analyze challenges, design criteria and opportunities to move towards more sustainable and competitive solutions.
