dc.description.abstract | Utilisation of potentially alkali–silica reactive aggregates requires reliable performance tests to evaluate the alkali–silica reactivity of various aggregate combinations, including their alkali threshold dependence on binder type. Several such performance tests have been used worldwide for more than 15 years, but none of the methods have proven to be reliable for use with all aggregate types and all binders. One of the objectives of RILEM TC 219-ACS (2007–2012) is to develop and validate one or more of such performance tests.
Several parameters may influence the results obtained in an accelerated performance test compared to the field behaviour. Based on a state of the art literature review, this paper discusses which parameters must be considered to be able to develop reliable ASR performance testing methods and provides some tentative recommendations. The internal humidity in the test specimens, the extent of alkali leaching and the storage temperature are of particular importance | nb_NO |
dc.description.sponsorship | ACKNOWLEDGEMENT. We greatly acknowledge all RILEM TC 219-ACS members and the TC Chairman and Secretary. We are particularly thankful to the authors that took part in the literature survey report performed within the task group “Performance testing”, in which has formed the basis for this review paper. The authors would also like to acknowledge COIN, the COncrete INnovation centre (www.coinweb.no) for the financial support to the PhD study of the principle author. | nb_NO |
