Abstract:

The effects of quartz particle size on the nature of hydration products in unstirred, autoclaved metakaolin-lime-quartz slurries with Ca/(Al + Si) and Al/(Al + Si) ratios of 0.80 and 0.13 were investigated. While hydrogarnet invariably appeared before 11 Å tobermorite when using either fine or coarse quartz, its formation was more prominent in the presence of coarse quartz. The breakdown of hydrogarnet and the formation of 11 Å tobermorite were delayed in the presence of coarse quartz, suggesting that when using aluminous additives under autoclaving conditions, quartz fineness is a deciding factor. The amount of hydrogarnet formed during autoclaving followed by its breakdown is significant in relation to the formation of 11 Å tobermorite. © 1998 Elsevier Science Ltd.
