Influence of acid-base equilibrium in the Na/sub 2/O-CaO-FeO-Al/sub 2/O/sub 3/-SiO/sub 2/-H/sub 2/O system on the structure and characteristics of man-made rock
The influence of acid-base equilibrium on the Na/sub 2/O-CaO-FeO-Al/sub 2/O/sub 3/-SiO/sub 2/-H/sub 2/O system was investigated in this work. Granulated slag from smelted nickel, copper, and lead was used as the silicate component; and aqueous solutions of Na/sub 2/CO/sub 3/ and Na/sub 2/O x SiO/sub 2/ were used in the alkaline component. The use of this raw material in alkaline slag binders is made possible by the high activity of the alkali metal compounds which interact with nonferrous metal slags to form low based calcium hydrosilicates of the tobermorite group, sodium-calcium zeolites of gmelinite composition, calcite, and hydrated iron-containing neogenics in the solidification products that serve as auxiliary structure forming elements. These conclusions are based on a nuclear gamma resonance (Moessbauer effect) study of the iron ions during the hydration of alkaline slag binders. The study showed that there is an acid-base equilibrium which accelerates the transformation of iron II into iron III oxide, making amphoteric properties possible in this system.
