Alkaline-sulphate activation processes of a Spanish blast furnace slag
Alkaline-sulphate activation processes of a Spanish granulated blast furnace slag (Avilés, Ensidesa) have been studied. Activator solutions used were: deionized water (as reference solution), Ca(OH)2 (3,5∙10-3N), NaOH (1N), Na2CO3 (2N), CaSO4∙2H2O (3,0∙10-3N) at 25ºC. The influence of the nature of...

| Summary: | Alkaline-sulphate activation processes of a Spanish granulated blast furnace slag (Avilés, Ensidesa) have been studied. Activator solutions used were: deionized water (as reference solution), Ca(OH)2 (3,5∙10-3N), NaOH (1N), Na2CO3 (2N), CaSO4∙2H2O (3,0∙10-3N) at 25ºC. The influence of the nature of alkaline or sulphate solution cation on slag activation process was verified. Sodium solutions decrease the induction period while calcium solutions increase it.
Slag reaction degree was also determined, likewise the nature of the different reaction products formed as a function of the activator solution nature. |
