Ability of the R3 test to evaluate differences in early ...

Ground granulated blast furnace slag (GGBS) is a glassy byproduct of pig iron production and is commonly used in concrete industry to replace cement and thereby lower the carbon footprint of the material. Large variations in reactivity exist depending on the GGBS physical and chemical features. Here we investigate the ability of three rapid calorimetric methods to evaluate the reactivity of GGBS.
