8 summarizes the relationship between basicity, main mineral phase and hydraulic reactivity of steel slag. It can be seen that the reactivity of steel slag increases with its basicity. However, free-CaO content also increases with the increase of the basicity of steel slag. The C3 S content in steel slag is much lower than that in portland cement. Thus, steel slag can be regarded as a weak portland cement clinker (Tang 1973). A speciality cement, steel and iron slag cement, which is composed mainly of steel furnace slag, blast furnace slag, cement clinker and gypsum, has been commercially marketed in China for more than 20 years (Sun and Yuan 1983, Wang and Lin 1983).

Particularly, a partially frozen or thawed solution may have different modulus and concentration from those of the whole system. 14. Alkali silicate solutions have very high buffer capacity. A sharp change in pH value is observed only after neutralization of the alkali in the solution. pH value is the most important characteristic determining stability of high-modulus silicate solutions, that is, their inclination to the formation of gel or coagulation. 14). As reported by Korneev and Danilov (1996), alkali silicate solutions tend to over-saturate.

This indicates that the mean condensation degrees of these silicate anions are similar. 12 Ranges of the 29 Si chemical shift of the silicate structural units (based on Hoebbel and Ebert 1988). 0 Percentage of structural units (%) Q0 Q1 2 Qcy−3 Q2 Q3 Q4 1 12 20 7 25 31 0 22 28 33 36 13 53 6 0 7 0 0 10% higher than those in a solution made from anhydrous Na2 SiO3 (Dent Glasser and Lachowski 1980). Concentration of sodium silicate solutions also affects the mean condensation degree of silicate anions.
