Rheological performance and compressive strength of superplasticized cementitious mixtures with micro/nano-SiO2 additions

Effects of the addition of nanosilica on the rheology, hydration and development of the compressive strength of cement mortars

“…This value is very close to the nS content that maximizes the density of fresh mortar (1.7%), as reported in a previous paper [38], and is consistent with the findings of other authors [14,23,26].…”

Evaluation of the mechanical properties and durability of cement mortars containing nanosilica and rice husk ash under chloride ion penetration

“…The addition of nanosilica was found to increase the compressive strength development of mortars. Some researchers [9][10][11][12][13][14][15][16] have reported a progressive increase of compressive strength with increasing nanosilica content, while others [17][18][19][20][21] obtained optimal proportions for lower dosages of additive due to agglomeration caused by difficulties to disperse the higher percentage of particles during mix.…”

Influences of nano-TiO2 on the properties of cement-based materials: Hydration and drying shrinkage

“…The increase of the amount of water needed when nano-particle is added could be due to its small size and great surface area, which will absorb more water on the surface [35,36].…”
