Abstract: This paper deals with the hydration process and the microstructure changes of Portland cement blended with blast furnace slag. The hydration process indicated by heat release was measured using a thermometric isothermal conduction calorimeter. The microstructure of hydration products and the morphology of C-S-H, CH, and unhydrated particles were examined by means of Scanning Electron Microscopy (SEM) and Energy Dispersive X-ray Analysis (EDX). The influence of factors, like water/cement ratio, curing age, and the amount of blast furnace slag on the hydration and microstructure was studied in detail. The results show that the microstructure of Portland cement blended with blast furnace slag is different compared to Portland cement paste.
