“…The ASR gel was collected from three different locations in the galleries of the Furnas dam. The ASR gel has been previously characterized by soft X-ray microscopy [24], NMR [25,26] and total scattering methods [27,28]. The NMR results indicated that the silicate network of the ASR gel can be characterized as a layered Q 3 -like and clusters of 3-dimensional Q 4 silicates while the pair distribution analysis showed that no distinct structural correlations can be observed beyond about 10 Å.…”

“…The surfaces of hydraulic concrete dams are subject to wear by erosion (American Concrete Institute, 1999), fissures caused by the pressure of crystallization of salts in the pores (Tambelli et al, 2006) and by exposure to contaminants (Irassar et al, 2003 ), causing defects and constant maintenance and repair applications.…”
