Abstract
Granulated blast furnace slags from VSZ Kosice was activated by using different alkalies such as NaOH, Na2CO3 and water glass. The influence of the slag fineness, curing conditions of the moulded specimens and the content of alkalies and silica module of water glass have been stu died. Results show that curing conditions have great effect on the str ength development. Slag activated in the presence of water glass had e xcelent mechanical properties, 28 days compressive strength up to 120 MPa was obtained.
