Abstract

The hydration of C4AF was retarded by the addition of Na2Si2O5 of up to approximately 0.1 mass% and the hydration completely stopped when it exceeded 0.1 mass%. Metastable phases, such as Ca2Al(OH)7 · 3H2O and Ca2Al2O5 · 8H2O, etc., were produced when C4AF was hydrated in Na2Si2O5 solution, whereas hydrogarnet was formed as the main hydration product when C4AF was hydrated in water. The ion concentrations of Ca and Al in the liquid phase decreased, and at the same time the period for hydrogarnet formation in the paste was delayed with an increase in the amount of Na2Si2O5 added to the liquid phase.
