- Emergence of nanotechnology in the oil and gas industry: Emphasis on the application of silica nanoparticles (2017, background): “[80] stated that the presence of nanosilica and silica fume accelerated the hydration of cement because a faster initial and final setting times were observed in cement pastes.”
- Incorporation of nano-materials in cement composite and geopolymer based paste and mortar – A review (2017, result): “Similar findings were observed from the previous research works that showed an increase in NS particles reduced the setting time significantly [41,47] and this is one of the important characteristics for a repair material [48].”
- Beneficial role of nanosilica in cement based materials – A review (2013, background): “The setting time of fresh cement paste and mortar were decreased by increasing the content of silica nanoparticles [47,48,51–53].”
- A review on the properties, reinforcing effects, and commercialization of nanomaterials for cement-based materials (2020, background): “In addition, compared to other nanoparticles, nano-SiO2 shows unique advantage in providing increased production of cement hydration Ca(OH)2, possessing faster pozzolanic reactivity, and an accelerating effect on the hydration of cement [66,67].”
- A review of dispersion of nanoparticles in cementitious matrices: Nanoparticle geometry perspective (2017, background): “Both the ionic composition of pore fluid of cement composites and the high ion-adsorption tendency of silica nanoparticles in aqueous media affect the stability of silica particles, causing significant agglomeration of these materials [13-15].”
- The effect of nanosilica addition on flowability, strength and transport properties of ultra high performance concrete (2014, background): “5, nS showed a considerably higher reactivity than silica fume at early ages (31%) which can be attributed to relatively higher specific surface areas of nS (Table 2) [33].”
- 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].”
