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.
Ms Ruchika Chaudhry Govil, Joint Secretary, Ministry of Steel, Government of India today said that non-usage of LD slag is a growing problem and the industry needs to learn from other countries?
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.
Mould powders or mould fluxes are synthetic slags which should fulfill different functions during continuous casting of steel, (1) as (i) protect the steel meniscus from oxidation, (ii) absorb inclusions floating up from the steel, (iii) provide thermal insulation to prevent the steel from freezing, (iv) provide the optimum level of horizontal heat transfer between shell and mould and (v) provide lubrication of the steel shell.
