【 摘 要 】

Application of various supplementary cementitious materials was adopted currently by number of research institutions worldwide. The main motivation is to find out predominantly environmental friendly technologies applicable in cement industry; however this technology is not new. Historically were various active mineral additives used in Ancient times and this technology was rediscovered at the end of 19th century with gradual development of cement and lime industry. This paper is focused on the long-term experimental study of pozzolanic reaction monitored in terms of thermogravimetry by the determination of the consumption of lime. Various types of ceramic powder were studied during two years and their activity was estimated using predictive method. Obtained results confirmed significant impact of the finesses on the reaction kinetics and also on the total hydration potential.
