Investigation of Accelerated Hydration in Nanosilica Incorporated Tricalcium Silicate using THz Spectroscopy [PDF]
arXiv, 2021 The incorporation of nanosilica in cementitious systems helps in accelerating the cement hydration process and early-stage formation of the main hydration product, that is, calcium silicate hydrate. Nanosilica reacts with the other key hydration product, calcium hydroxide to form additional calcium silicate hydrate. In this work, Terahertz spectroscopy

A Cost-Effective Slag-based Mix Activated with Soda Ash and Hydrated Lime: A Pilot Study [PDF]
, 2023 The present study explores a cost-effective method for using activated ground granulated blast furnace slag (GGBFS) and silica fume (SF) as cement substitutes. Instead of activating them with expensive alkali solutions, the present study employs industrial-grade powdered sodium aluminate (SA) and hydrated lime (HL) as activators, reducing expenses by ...
