Highlights Calcium silicate hydrate nanoparticles synthesized under ambient conditions. The particles were added to a cement composite to confirm hydration properties. The calcium silicate hydrate nanoparticles acted as nucleation sites. Concentration of generated harmful ions was reduced through a cleaning procedure. Initial hydration calorific value and compressive strength increased.
Abstract This study aims to synthesize calcium silicate hydrate (CSH) nanoparticles at room temperature using a liquid-phase reaction method, to incorporate the synthesized material into a cement composite, and to study its hydration characteristics. The optimal amount of polycarboxylate-based dispersant, in terms of nanocrystal size and CSH particle aggregation state, was obtained using scanning electron microscopy. The concentration of the generated harmful ions during the synthesis was reduced via a cleaning procedure. The experiments confirmed that the CSH nanoparticles acted as nucleation sites. Moreover, the initial hydration calorific value and early-age compressive strength increased with the amount of CSH nanoparticles.
