Tricalcium aluminate hydration in the presence of lime, gypsum or sodium sulfate
TL;DR: In this article, the influence of Ca(OH) 2, CaSO 4 ·2H 2 O and Na 2 SO 4 on the C 3 A hydration was examined in order to study the retardation mechanism caused by lime and/or gypsum additions.

Compositions of Solutions in Contact with Hydrating Tricalcium Silicate Pastes
TL;DR: In this article, the ionic product for calcium hydroxide (CH) was calculated as a function of time and correlated with calorimetric measurements and crystal growth data.

Silicate polymerization during the hydration of alite
J. Hirljac,Z.-Q. Wu,J.F. Young +2 more
TL;DR: The influence of admixtures and curing temperature on silicate polymerization during the hydration of alite was studied in this paper, where the major species identified in the hydrated pastes were dimer, linear pantamer, and linear octamer; at later ages, particularly at higher temperature, higher polymers are formed.

Formation of Calcium Hydroxide from Aqueous Suspensions of Tricalcium Silicate
Zhao-qi Wu,J. Francis Young +1 more
TL;DR: In this paper, the release of Ca2+ and OH from tricalcium silicate into the aqueous phase was monitored over the first few hours and the analytical data were compared with the rate of heat released from companion pastes.
