Authors: Zhijun Tan, Geert De Schutter, Guang Ye, Yun Gao, Lieven Machiels Abstract: This paper investigates the influence of slag particle size on its hydration speed at particle level in the early age. Slags were separated with sieves into groups of different size fractions, considering a wide range of sizes. The chemical compositions of each […]

It is mentioned previously that the reactivity of slag is influenced by its fineness of grinding (specific surface area) that is determined by the sizes of slag particles. The finer the slag particles, the larger the surface area, which means higher hydration degree of slag. However, if disregarding the fineness, in other words, take two […]
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 […]
