TL;DR: Amorphous nano-silica (nS) particles were incorporated in cement pastes and mortars, and their effect on the fresh state behavior was analysed as mentioned in this paper, where the influence of nS content was better observed on yield stress when compared with plastic viscosity values (the first increased about 66.5% while the latter just increased 3.6%).

...Some authors defend that the appropriate percentage of nS has to be small (1–5 wt%) due to agglomeration caused by difficulties to disperse the particles during mix [6,8,10,11], while others indicate that the improvement of the properties can also be achieved with higher dosages, of about 10 wt%, if proper adjustments are made to the formulation in order to avoid excessive self-desiccation and micro-cracking that could hinder the strength [12]....

Abstract: An understanding of the performance of portland cement-based materials requires knowledge at the microstructural level. Developments in the instrumentation of several techniques have led to improved understanding of the composition, morphology, and spatial distribution of the various products of cement hydration. In particular, our understanding of the nature of the nearly amorphous calcium silicate hydrate (C–S–H) phases – which are the principal binding phases in all portland cement-based systems – has been advanced by developments in solid-state NMR spectroscopy and analytical TEM. This paper presents an overview of the nature of the hydration products formed in hardened portland cement-based systems. It starts with the most straightforward cementitious calcium silicate systems, C3S and β-C2S, and then considers ordinary portland cement and blends of portland cement with silica fume, ground granulated iron blast-furnace slag, and finally alkali hydroxide-activated slag cements.
