Retardation effect of styrene-acrylate copolymer latexes on cement hydration (2015, background): “The acceleration of VVC polymer was considered to be due to the presence of Cl− ions in pore solution, since many chloride salts are known as accelerators [11,12].”
Compatibility between polycarboxylate-based admixtures and blended-cement pastes (2013, positive): “Previous studies [45,46] have explained that the delay of the hydration process induced by PCEs could be due to two main reasons (a) their adsorption onto the cement particles and (b) due to the growth kinetics and morphology of early hydrates.”
Effects of the charge characteristics of polycarboxylate superplasticizers on the adsorption and the retardation in cement pastes (2015, background): “Namely, the hydration rate at any time in the acceleration period is solely determined by the total amount of hydrate nuclei at thatmoment [22,23].”
Influence of triethanolamine on the hydration product of portlandite in cement paste and the mechanism (2016, background): “[7] pointed out that an increase in dissolution of iron contributed little to the enhanced strength at TEA dosage of less than 0.”
Correlations of the dispersing capability of NSF and PCE types of superplasticizer and their impacts on cement hydration with the adsorption in fresh cement pastes (2015, background): “[10] reported that the maximum hydration rate in the acceleration period is associated with the amount of hydrate nucleus.”
Advances in understanding ye'elimite-rich cements (2019, background): “Based on several results from different studies, it has been hypothesized that the adsorption of saccharides on hydrating minerals contributes to their effectiveness in slowing hydration [152,153].”
Advances in characterizing and understanding the microstructure of cementitious materials (2019, background): “…complexity of the concrete mixture design, the interactions of the various types of admixtures with the mixture constituents, and the stringent requirements for the concrete performance require a deep understanding of the interactions between the cement and the chemical admixtures [8,20].”
