Originální abstrakt

The effect of curing temperatures on the hydration of two binary systems comprising of Portland cement (PC) blended by metakaolin (MK) and blast-furnace slag (BFS) in two relative mass ratios (6/4, 5/5) was studied by means of isothermal calorimetry and combined TG/DSC technique in the temperature range of 30–60 °C. Higher curing temperatures accelerated the initial hydration reactions, especially in the case of more reactive MK-blended samples. However, except the lower replacement level of PC by BFS, all other samples displayed slowdown of hydration at later stages. The use of MK together with curing at 50 and 60 °C even resulted in the lower ultimate hydration degree after 48 h when compared with corresponding samples cured at 30 °C. Deceleration effect of higher curing temperatures was demonstrated mainly by decreasing amount of CSH phases. Pozzolanic activity of supplemental materials was affected by curing temperatures less than primary hydration reactions.
