MINI SESSION: Impact of Aggregates on the Sustainability and Durability of Concrete
Tuesday, October 28, 2025 11:00 AM - 12:00 PM, H - Tubman A&B
This session explores key aspects of concrete sustainability and durability linked to aggregate characteristics that may affect both short- and long-term performance of critical infrastructure. Certain aggregate types are known to contribute to deleterious reactions, such as alkali-silica reaction (ASR) and freeze-thaw (FT) damage, which can significantly compromise service life. A thorough understanding of the mineralogical and physical properties of aggregates is essential for anticipating and mitigating these durability risks. The session emphasizes the importance of rigorous aggregate selection, detailed characterization, and consistent quality control practices. These measures are fundamental to achieving resilient, long-lasting, and sustainable concrete structures.Learning Objectives:(1) Describe the impact of aggregates on the short and long-term performance of concrete and propose better ways to use aggregates towards low global warning potential;(2) Explain the main durability related issues in concrete associated to aggregates;(3) Evaluate new protocols proposed to diminish durability issues in concrete related to aggregates;(4) List advanced protocols to better use aggregates and thus diminish the carbon footprint of concrete construction;(5) Discuss suitable pathways to decrease durability related issues associated to aggregates and increase sustainability of concrete construction.This session has been approved by AIA and ICC for 1 PDH (0.1 CEU). Please note: You must attend the live session for the entire duration to receive credit. On-demand sessions do not qualify for PDH/CEU credit.
