摘要：

The autoclave products of reduced steel-slag of an electronic furnace mainly containing C3MS2 phase were detected. The hydrothermal products of this slag included calcio-chondrodite, brucite, and hydrogarnet phases. When suitable (CaO+MgO)/SiO2 molar ratios were chosen, C3MS2 can react with SiO2 to produce calcium silicate hydrates tobermorite, xonotlite, gyrolite, and truscottite phases with different saturated water vapor pressures. The phase brucite was present along with tobermorite, whereas phases Mg-xonotlite, Mg-gyrolite, and Mg-truscottite can rarely coexist with brucite. Hydrogarnet phase disappeared when Mg-truscottite was formed. (C) 1997 Elsevier Science Ltd.
