In order to examine the possibility of incineration of inderstrial by-product and wastes which contains a large percentage of chlorine by the cement kiln, measured heat of hydration, setting time, flow, change of length, compressive strength of OPC by the amount of KCl. The result was that a shorter setting time, a lower flow, a increasing the degree of initial shrinkage, a increasing of compressive strength before 3 days and decrease after 7 days by the induction period is shorter as promote the hydration with KCl.
Key words: Opc, KCI, Hydration
