- Abstract
- The purpose of this study is to provide the basic data to determine heating temperature and damage degree of admixture mixedconcrete and evaluate the quantitative chemical composition of admixture such as blast furnace slag and fly ash mixed concrete ateach temperature as exposed high temperature. TGA and XRD were conducted to evaluate the amount of calcium hydroxide(Ca(OH)2) and calcium carbonate (CaCO3) quantitatively and analyze the chemical composition in accordance with the kind ofadmixture and heating temperature. The result of TGA experiment is as mixing ratio increases the weight ratio of calcium(Ca(OH)2) is decreased and the weight ratio of calcium carbonate (CaCO3) is increased.
