Investigating the effect of the cement paste and transition zone on strength development of concrete containing nanosilica and silica fume (2015, background): “This result may have been due to the large aggregation (firmly-held clusters) or agglomeration (loosely-held clusters) of nanoparticles, primarily because of their high specific surface area and van der Waals force; consequently, formation of weak spots throughout the microstructure of the cementiti”
Review on concrete nanotechnology (2016, background): “Illustration of the filling effect of NS agglomerates: (a) The smaller agglomerates act as fillers to release some free water in the gap to enhance the fluidity of the paste; (b) The larger agglomerates cannot act as fillers; they tend to push away the particles around them, resulting in an increase”
SCC modification by use of amorphous nano-silica (2014, background): “the formation of a destabilizing gel with high water retention capacity (in form of bound water) [61–63].”
