Abstract
SILVA, C. S. et al. Recovery procedures for foundation elements with alkali/aggregate reaction problems. Documental research. Rev. ALCONPAT [online]. 2021, vol.11, n.2, pp.124-145. Epub Sep 12, 2022. ISSN 2007-6835. https://doi.org/10.21041/ra.v11i2.490.
The alkali-aggregate reaction (AAR) is a problem that has affected numerous foundations. This study, through an investigation of fifty foundations, seeks to create a profile of the recovery processes through consultations with inspection companies that have carried out recoveries in the city of Recife and neighboring areas. The methodology consisted on the application of a survey with seventeen questions. The results obtained made possible to establish similarities in the foundations affected, the diagnoses, processes applied during recovery, advances in materials, conditioning factors for the use of the reinforcement, and costs, and also identified the foundations where an inspection window was left for future checks. The results conclude with an evaluation of the treatments for foundations affected by AAR.
