- Influence of Mechanochemical Treatment of Lime-Silica Mixtures on Gyrolite Formation
この論文をさがす
説明
Gyrolite (Ca8Si12O30 (OH) 4·7H2O) was hydrothermally prepared in a stirred suspension at 180°Cusing mechanochemically treated starting mixtures of lime and amorphous precipitated silica at the theoretical Ca/Si ratios of 0.67 for gyrolite and 0.50 for the Zphase. The starting materials were treated by planetary ball milling for 15 min to 8 h at room temperature. With increased milling time, Ca (OH) 2reacted with silica to make a C-S-H like phase having a broad XRD peak centered at 0.30 nm. The C-S-H like phase contained a partly sheet-like silicate anion structure. Using the mechanochemically prepared mixture, with a Ca/Si=0.50 the hydrothermal reaction sequence is mechanochemically formed C-S-H→Assarsson's Z-phase→gyrolite and with a Ca/Si=0.67 mechanochemically formed C-S-H→gyrolite. However, using the mixtures at Ca/Si=0-67 without milling, the sequence is CaO+silica→hydrothermally formed C-S-H→gyrolite.
