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 […]
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 […]
The exact composition of slag varies over a range. In general, factors that determine the suitability of slag for usage in composite cement mainly include the fineness of grinding, glass content and the chemical composition. Fineness Like most of other cement materials, the reactivity of slag is influenced by its surface area. Increased surface area […]
