Description
A commercially available, sulfate-resisting Portland cement and two cement formulations derived from it by addition of 20 vol.% silica fume and 35 vol.% fly-ash, respectively, were leached in Standard Canadian Shield Saline Solution containing Ca-bentonite or Na-bentonite at 150 degrees C for 14 days. The presence of clay accelerates the rate of release of various elements from the cements. The pH of the leach solutions plays a dominant role in the kinetics of element release
