Abstract: This paper investigates the influence of temperature on the hydration of Limestone Calcined Clay Cements (LC3). The increase from 20°C to 40°C leads to an acceleration of hydration. Both clinker hydration and metakaolin reaction are faster. However, similar amounts of reacted clinker and metakaolin are measured at late ages. The influence of temperature on C-A-S-H density was also studied. The grey level of the C-A-S-H was determined and the differences observed between plain cement and LC3 blends are related with the difference of chemical composition. There is no clear evidence that the density of C-A-S-H increases with temperature.
