Silica fume-basic blast furnace slag systems activated by an alkali silica fume activator

Rousekova, I. / Bajza, A. / Zivica, V.

This paper deals with the results of research on binder systems based on the use of silica fume. The data obtained show that the optimal proportion of blast furnace slag and alkali activator prepared from silica fume permits the obtaining of interesting materials from the point of view of their technical properties as well as from the possibility of utilizing industrial wastes. The composite developed is hydraulic. It is possible to state that these kinds of binding systems have shown promise of future use. This procedure allows for an increase in the compressive strength of the composite and a significant increase in its resistance to water (to improve the hydraulicity of the binder system). The improved properties of composites containing the alkali activator over those prepared with NaOH confirm the higher effectiveness of the alkali silica activator over the NaOH.
