Systematic review on alkali-aggregate reactions: comparative overview of studies carried out in Canada and Brazil

Abstract

The objective of this research is to compare the performance of Canada and Brazil in studies related to alkali aggregate reaction (AAR) in concrete, through a qualitative, quantitative and systematic review of the literature, in addition to using the VOSviewer software for co-analysis, citation and bibliographic coupling. The collected data indicate that Canada is the country that most stands out in terms of AAR research in the world, and Brazil is in seventh place. The work presented the research centers of the two countries, the existing methodologies for assessing AAR and the panorama of research on the subject in Brazil. Finally, the work showed the emerging themes about AAR and knowledge gaps.
