Influence of nano-SiO2 on properties of fresh and hardened high performance concrete: A state-of-the-art review
TL;DR: In this article, a detailed review on the fresh properties, mechanical properties and durability of high performance concrete containing nano-SiO2 (NS) particles is presented, and the incorporation of SiO2 nano-particles significantly improves the mechanical properties of HPC though the flowability of the fresh concrete is decreased by the usage of NS.

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.
