Study on CaO-Al2O3-H2O colloid system crystallization and nucleation centre

摘要

The broad field of colloid chemistry is broadly integral part of nanoscience. It's now actually see the atoms, and development was hard even to imagine only a few years ago. So today from the view from high technological developments that tend to amaze. There have been many investigations for speeding up hydration and crystallization process and formation of new nucleation center for the hydrated system. The investigation has primarily focused on the influence of amorphous aluminous-silicate as K-krent, which was obtained from Kaoline, to the three calcium aluminate phases' hydration as key compound of cement's hydration process. This paper will present the results on crystallization process CaO-Al2O3-H2O system by using crystallizing component as K-krent 15 %. This report is discussed C-A-H system various hydro-aluminate calcium compounds and their structure morphology from their colloid systems. C3AH6 large amount in cubic crystals were formed, in case of doping K-krent to the C3A phase hydration. It was related to making new a nucleation center for crystallization processes when adding this activated powder state mineral in it and accorded to general regularity on hydration and crystallization process.
