Title: Technical Committee on ASR Inhibition Measures and Diagnosis Based on its Action Mechanisms
Author(s): Kazuyuki TORII, Kazuo YAMADA, Hirohisa KOGA, Yoshimori KUBO, Toru YAMAJI
Appears on pages(s): 1-20
Keywords: Alkali-silica reaction, petrography, aggregate, reactivity assessment, inhibition measures, diagnosis, current state of deterioration.
Abstract:This technical committee updated information regarding material aspects of alkali-silica reaction (ASR) since the former committee in the 1980s, reviewing the recent developments of ASR testing for concrete aggregate and ASR diagnosing for damaged concrete structures, and thereby proposing an ideal preventing way of ASR in the future. The committee also examined the current state of ASR deterioration of existing structures, which should be a field of verifying the validity of theoretical study, accompanying a new aspect of petrography/mineralogy. Guidelines for applying petrographic techniques to aggregate assessment and deterioration diagnosis were also provided. Various other issues related to ASR were summarized as well.
