The reaction of CaO particles in a cement clinker is described by a simple model for diffusion‐controlled dissolution of spheres. The experimental results agree well with those predicted from data obtained in independent diffusion experiments. Under certain conditions it is possible to determine the maximum size of CaO particles which can react with C 2 S to give C 2 S within a given reaction time; further, for a given size distribution of CaO particles, the content of free CaO in the clinker after a given burning time can be estimated.
