Abstract: Using several types of Portland cement and blast furnace slag powder(BFS), relationship between the hydration of BFS blended cement and the microstructural evolution were studied. The rate of consumed calcium hydroxide from BFS hydration do not have the constant value, gradually decreases as hydration progresses. The capillary pore volume of BFS blended cement is larger in lower region of hydration degree, and remarkably decreases as hydration progresses. The amount of drying shrinkage of Portland cement and BFS blended cement mortar can be explained by the volume fraction of C-S-H gel in solid phases, the larger shrinkage of mortar with the lager amount of C-S-H.
