The Effects of Addition Two Different Types of Trass to the Clinkering Reaction

Abstract

In this study, instead of clay the effect of trass - which is used as a component for clinker production in the cement industry and has properties that are significant for agriculture - are researched. The clinkering properties of raw material compositions which are prepared according to the constant Lime Saturation Factor (LSF) degree were considered in relation to sintering at fixed temperature (1450 oC). Two different clinkers - namely trass 1 which is added to clinker 1 and trass 2 which is added to clinker 2 - were produced from the raw material compositions prepared at a constant LSF. The clinkering reaction was determined by the measurement of the free CaO (FCaO) value. According to the FCaO content and the amount of C3S test results, clinker 1 is preferable to clinker 2. Because of the C3S phases are 70,43 % and 42,72 % respectively.
