Effects of nano-silica on the strength development of geopolymer cured at room temperature (2015, background): “[42] found that the nano-silica particles with high specific surface area constituted a highly reactive siliceous media in the alkaline environment.”
The effect of nanosilica addition on flowability, strength and transport properties of ultra high performance concrete (2014, background): “Additionally, the incorporation of nS particles can accelerate the hydration process of C3S clinker phase due to the large and highly reactive surface of the nanoparticles [41–42].”
Durability properties of high volume fly ash concrete containing nano-silica (2014, positive): “However, it can be controlled by carefully adding superplasticizer and by appropriate curing methods [32, 33].”
SCC modification by use of amorphous nano-silica (2014, background): “It was demonstrated in [9] that the reactivity of nano-silica is controlled by its specific surface area and the amount of Q(2) 3 (silanol) Si–OH groups, which cover the nano-particle.”
Early hydration and setting of Portland cement monitored by IR, SEM and Vicat techniques (2009, background): “The dip in the absorption spectrum at 800–970 cm−1, which deepens with time, is due to the dissolution of the C3S clinker phase [39].”
