Calcium chloride acceleration in ordinary Portland cement
Magazine of Concrete Research, 2018Early-age hydration of ordinary Portland cement is now acknowledged to originate from nucleation and crystal growth of calcium–silicate–hydrates.

On the hydration of Portland cement
Proceedings of the Royal Society of London. A. Mathematical and Physical Sciences, 1978When Portland cement is contacted with water, calcium ion is rapidly leached from the solid to form calcium hydroxide solution but only traces of silica are found in the aqueous phase. It is proposed that the hydrated, calcium-depleted surface of grains consists of low molecular mass silicic acids and that these interact with dissolved ...

The hydration of Portland cement
Proceedings of the Royal Society of London. A. Mathematical and Physical Sciences, 1978Electron microscopy and conduction calorimetry have been employed to study the hydration of Portland cement.In situstudies of wet cement pastes in an environmental cell in the high voltage microscope confirm that the reaction involves two stages: (a) the rapid initial formation of gelatinous hydrate coatings around the cement grains and, (b) after a ...

Reinforcing effects of graphene oxide on portland cement paste
, 2015In this experimental study, the reinforcing effects of graphene oxide (GO) on portland cement paste are investigated. It is discovered that the introduction of 0.03% by weight GO sheets into the cement paste can increase the compressive strength and ...
