Calcined kaolinite–bentonite clay blends as supplementary ...

01/05/2015  Two clay blends, kaolinite–calcium bentonite and kaolinite–sodium bentonite were calcined at temperatures of 650 °C, 830 °C and 930 °C, and compared with both a reactive pozzolan and a non-reactive quartz filler. Rietveld quantitative x-ray diffraction and thermogravimetric analysis (RQXRD-TGA) were used as methods to assess the effectiveness of a specific temperature at reducing clay ...
