• Effect of nano-silica on the mechanical and transport properties of lightweight concrete (2015, methodology): “Previous literature has well documented that NS can accelerate the hydration of cement or blended cement [10,17,18,21,25,26].”
• Effects of colloidal nanosilica on rheological and mechanical properties of fly ash–cement mortar (2013, background): “[14,15] found that the physical and mechanical properties of high-volume fly ash/slag systems can be greatly enhanced.”
• Effects SiO2/Na2O molar ratio on mechanical properties and the microstructure of nano-SiO2 metakaolin-based geopolymers (2014, background): “These surface atoms accelerated the reaction rate of the system because of their high activity and instability [24].”
• Durability properties of high volume fly ash concrete containing nano-silica (2014, result): “The present finding is in agreement with Islam’s [40] findings which showed an improvement on compressive strength of HVFA concrete at early ages due to NS addition.”
• Nanomechanical characteristics of interfacial transition zone in nano-engineered concrete (2021, background): “[13,14] suggested that the presence of nanosilica can refine the pores in the ITZ and prevent the ITZ from being the weakest phase in concrete at the mesoscale.”
• Investigating the effect of the cement paste and transition zone on strength development of concrete containing nanosilica and silica fume (2015, background): “It was confirmed that although both nS and SF contain highly reactive amorphous silica, the effect of the former – largely due to its much smaller size (about 10 times) – rather than the latter was obviously more substantial [15,47].”
