Özet
The chemical compositions of the pore solution expressed from commercial calcium sulfoaluminate-belite cement paste at selected intervals of 1, 3, 7, 14, 30 and 60 days, cured at 20 degrees C, have been determined, pH was measured in the range 12.8-13.1, changes in concentrations of Na, K, Ca, Al, Si, CI, Br and SO42- were determined between I and 60 days of curing. The main components in the pore solution were Al and K: Na, Ca, CE, Br and SO42- concentrations were low, and the Si concentration was below the detection limit. Potassium is slowly sorbed by the solids, and its concentration passes through a maximum at similar to 3 days.
