Emanation thermal analysis (ETA) has been applied to the investigation of hydration of cement at temperatures of 20, 35, 45, 65 and 85 °C. ETA measurements enabled us to assigne the time intervals where different stages of hydration process Lake place. The structure of intermediate products, controlling the mechanical properties of the cement paste during hardening can be tested by ETA, ETA results are compared to measurements of penetration resistance. Using NETZSCH-equipment, ETA can be carried out automatically at required temperature and in gas medium with defined humidity, i.e. it can be used for testing cements during setting and hardening directly in technological conditions.
