Abstract:

The effects of quartz particle size on the formation of hydrogarnet in unstirred, autoclaved kaolin-lime-quartz slurries with Ca/(Al + Si) and Al/(Al + Si) ratios of 0.8 and 0.13 were investigated. The initial lime-kaolin reaction was retarded only when fine quartz was used. The slower release of silicate anions from coarse quartz prolonged the stability of hydrogarnet while retarding the formation of 11Å tobermorite. Both the type of aluminous source and the extent of release of silicate anion from the silica source influence the formations of hydrogarnet and 11 Å tobermorite as well as the stability of the hydrogarnet. The interdependency between aluminous and siliceous sources is evident. © 1998 Elsevier Science Ltd.
