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. […]

The latent hydraulic property of slag means no hydration products could be observed when slag is solely placed in contact with water, though surface analysis using X-ray photoelectron spectrometry showed that the surface of slag was modified as soon as it came into contact with water making a protective film lacking Ca2+ that prevent further […]
Though the chemical reaction of the fine particles of limestone in cement paste is limited to a low extent due to its inert property, the addition of limestone particles has significant effect on the microstructure development. Research conducted by Sellevold et al. using mercury intrusion method showed that specimens containing 12% CaCO3, which have the […]
