Study on Formation of Cement Clinker from the Mixture of Oyster Shell, Casting Dust and BOF Slag
ABSTRACT
The mixtures which are in the chemical composition of Portland cement were prepared from oyster shell, casting dust and BOF slag. The clinkerbility and the behaviour of formation of clinker minora]s were studied using the mixtures mainly by the mineral and microstructural observation. By virtue of the characteristics of starting raw materials, the clinkering temperature was lower as much as 100$^{circ}C$ than that of a mixture prepared from normal raw materials. Uncombined calcium oxide was vanished entirely below 1350$^{circ}C$. and the formation of major cement minerals such as alite and belite could be nearly accomplished without too much liquid phase within 1400$^{circ}C$.
Key words: Portland cement, Wastes, Oyster shell, Clinkerbility
