Alkali-Silica Reaction: Research Needs & the Link to Practice Description by Prof. Jason Ideker, US

Alkali-Silica Reaction: Research Needs and the Link to Practice
Description

Speaker: Dr. Jason H. IDEKER, Professor, Oregon State University, United States

Host: Prof. Karen Scrivener, Ecole Polytechnique Fédérale de Lausanne, Switzerland

This presentation will cover alkali-aggregate reaction in concrete with a focus on alkali-silica reaction (ASR). A brief background of the reaction mechanisms and methods to prevent ASR will be covered. The talk will highlight some of the author’s current research and extend to a broader discussion on the research needs to engage the PhD students in the audience. Key references will be provided to enable further self-study or support for ongoing research. The link between accelerated testing methods, field performance and the current state-of-practice will be given. International standards efforts including ASTM and RILEM will support this discussion.

Dr. Jason H. Ideker is a Professor at Oregon State University. He is the Editor-in-Chief of CEMENT and Co-Editor-in-Chief of ASTM’s Advances in Civil Engineering Materials. Dr. Ideker’s main research areas are in service-life of concrete with a focus on early-age behavior of high-performance cementitious materials, prevention and test methods for alkali-silica reaction and durability of calcium aluminate cement systems.
