✦ Synopsis

The influence of Cd0 on the hydration of 3Ca0.A1203 at 25°C was studied by X-ray diffraction, scanning electron microscopy, thermal gravimetry, and calorimetry for hydration times less than one day. The Cd0 had a small effect on the thermal characteristics of hydration. Slightly less heat was liberated when Cd0 was added to the 3Ca0.A1203. The presence of Cd0 increased the formation of the cubic hydrated phase. The cadmium was retained in the matrix as Cd(OH)2.

Through the carbonization of 3CaO.A1203.6H20, the phase 3CaO.Al203.11H20 is formed first, nevertheless in the following period it decomposes into AI(OH) 3 and vaterite, which later is transformed into calcite. The degree of decomposition of C3AH 6 increases with time of reaction, concentration of CO
