The early-age performance of concrete is determined by the properties of the cementitious binder and the evolution of chemical reactions therein at early ages.The composition of particles, and hence their reactivity may be size-dependent, e.g., especially in case of materials such as fly ash.Since reactivity is a key variable which dictates the progress of reactions, it would be valuable to separate cementitious minerals into well-defined sizes, wherein, by eliminating dispersion in size, the effects of composition on reactivity can be systematically unraveled.
