Limestone is commonly considered to have a pure filler effect. However limestone powder cannot be considered totally inert due to the formation of carboaluminates; the impact of these products on heat release and microstructure formation may be considered secondary [11]. Increasing the specific surface of the reactant can increase the reaction rate. But for SCMs the effect …
