Application of thermogravimetric analysis for characterization of clay as supplementary cementitious material

High-volume cement replacements can potentially reduce carbon dioxide emissions caused by cement production. Current research aims to find the most optimum locally available materials that can serve as replacement for cement. Thermogravimetric analysis (TGA) ranks among the methods used to characterize potential materials. This paper presents results of such analysis performed on six clay soil samples. The approximated quantity of clay mineral, calculated by means of TGA, is compared with the reactivity test (R3 test) using isothermal calorimetry. The results indicate that selected soil samples can be considered as low-grade kaolinitic clays. Nevertheless, they show a good correlation between clay mineral content and reactivity of the sample
