As it is well-known, the activation of latent slag in blended cement is implemented by calcium hydroxide (CH, Ca(OH)2) which is the main cause maintaining the high pH value of pore solution. The activation happens as the break of glass layer of slag particles. However, how does the break take place in detail? Researchers have […]

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. […]
Many XRD analysis results have shown the main hydration products of slag blended cement are essentially similar with that of pure Portland cement, except the amounts of CH found by this method or other are in varying degrees and less than those that should be given by the pure Portland cement constituent if the slag […]
