TLDR
In this paper, the effects of nano-silica incorporation on an eco-friendly alkali activated slag-fly ash blends were investigated, and the results indicated that as the nano silica content increases, the slump flow is significantly reduced, and reaction process is slightly retarded according to the setting time and isothermal calorimetry results.About:

Characteristics of cement mortar with nano-SiO2 particles
TL;DR: In this paper, the properties of cement mortars with nano-SiO 2 were experimentally studied, and the results showed that the compressive strength of mortars containing nano SiO 2 particles was significantly higher than those of those containing silica fume at 7 and 28 days.
