The Effect of Silicious Raw Materials on Mineralogical Properties in Clinkering Process.
To clarify influences of silicious raw materials on mineralogcal and petrological properties in clinkering process clay, shale, quartzite, sand and coal ash have been used as silicious raw materials. The tests on thermal properties, reactivity and burnability of raw mixtures which have different silicious raw materials respectively have been made by means of X-ray diffractometry, differential thermal analysis, optical microscopy and transmission electron microscopy. Limestone contains coarse crystalline grains which show 0.1-1.0mm and its decarbonation temperature is 86$0^{circ}C$. Reaction temperatures among raw mixtures have been determined by X-ray diffractometry and their results are as follows; clay minerals under 1, 00$0^{circ}C$, mica group, 100$0^{circ}C$-110$0^{circ}C$, feldspar group, 1, 10$0^{circ}C$-1, 20$0^{circ}C$ and quartz 1, 20$0^{circ}C$-1, 30$0^{circ}C$. Burnabilities of raw mixtures of different temperatures have been found that they mainly depend upon their mineral contents in silicious raw materials and their order is as follows; $claygeq shalegg quartzite geq sand$.
