Abstract
The influence of CdO on the hydration of 3CaO.Al2O3 at 25 degrees C wa s studied by X-ray diffraction, scanning electron microscopy, thermal gravimetry, and calorimetry for hydration times less than one day. The CdO had a small effect on the thermal characteristics of hydration. S lightly less heat was liberated when CdO was added to the 3CaO.Al2O3. The presence of CdO increased the formation of the cubic hydrated phas e. The cadmium was retained in the matrix as Cd(OH)(2).
