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 […]
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 […]
