Effects of carbonation on cadmium S/S systems have also been investigated. Evidence is presented from FTIR results that the hydration of OPC is retarded due to the formation of calcium hydroxycadmiates, which result from the surface reaction of [Cd(OH) 4] 2‐ with calcium ions at or on the surface of the cement grains. Considerable insight has ...
