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 with very fine porosity, and large slag […]

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 neat OPC pastes are C-S-H gel, Ca(OH)2, AFm and AFt. […]
