Characteristics of cement mortar with nano-SiO2 particles
TLDR
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.About:

Microstructure of cement mortar with nano-particles
TL;DR: In this paper, the mechanical properties of nano-Fe2O3 and nano-SiO2 cement mortars were experimentally studied and the experimental results showed that the compressive and flexural strengths measured at the 7th day and 28th day of the cement mortar mixed with the nano-particles were higher than that of a plain cement mortar.
