Features of microstructure development in the inner product of reacting slag in blended cement

The morphology of inner product region derived from alite or belite is identical to those present in neat OPC paste. In mature pastes, fully hydrated small grains of both alite and GGBFS often display a coarse morphology.

Generally, inner product in larger grains has a dense homogeneous morphology ......

Features of microstructure development in the outer product of reacting slag in blended cement

Similar to Portland cement, microstructure of slag hydrate could also be classified as inner product, which formed within the boundaries of the original anhydrous grains, and outer product that formed in the originally water-filled spaces.

The major phases present in the outer product region of nea......
