The rate of heat evolution of slags during the early age of three days was monitored by an isothermal calorimeter (TAM AIR, USA), under a constant temperature of 20[degrees]C.

Based on these previous investigations, the present work focuses on the reactions of TiN and [Ti.sub.2][O.sub.3] in contact with CaO-[Al.sub.2][O.sub.3]-Si[O.sub.2]-MgO
slags and in Ti-stabilized ferritic stainless steel.
In alkali-activated
slag, the presence of [Na.sup.+] and OH- in the pore solution is likely to be affecting the results of the chloride test (ASTM C 1202), as [Na.sup.+] will be expected to counter-diffuse as the [Cl.sup.-] ions are electrically driven into the pore network, leading to an increased charge transfer during the test, so the fact that Figure 6(b) shows a lower charge passed value for alkali-activated
slags than the Portland cement reference can be taken to indicate that the actual chloride movement through the materials is likely to be much slower.
Nearly 12 million tons of BOF
slag is produced in Europe per year.
The temperature dependence of electrical conductivity was measured at CO/C[O.sub.2] = 1 for all
slags. The effect of temperature on total electrical conductivity was shown in Figure 1.

slags," Journal of Cleaner Production, vol.
The environmental conformity of
slags has been investigated for years, which normally should be judged by their leachability.
