Abstract: This paper describes investigations of 10 to 12 years old hardened cement pastes made of different cements and additives. Two ordinary Portland cements with different alkali contents and a blast furnace slag cement were chosen. Fly ash, silica fume and quartz powder were used as additives. The cement pastes were sealed and stored at 20°C. The investigations included thermogravimetric analysis, chemical analysis of the hardened cement paste and the pore solution, mercury intrusion porosimetry and differential scanning calorimetry. The aim of this research work was to obtain insight in long-term reactions of cements and additives.
