STUDY OF THE ZEOLITIZATION PROCESS OF FLY ASH USING AN ORTHOGONAL ARRAY OF TAGUCHI EXPERIMENTAL DESIGN

Zeolitization of fly-ash by a direct route and a fusion method (two-step process) was studied using an orthogonal array of Taguchi experimental design. The effect of different processing conditions, such as type and concentration of the mineralizing agent, fusion and crystalhzing temperatures and ti...
