A new modification of belite‐rich cement, a “remelted belite cement,” exhibits higher hydration activity and better grindability than conventional belite‐rich cement. The belite constituent in the new cement completely undergoes a remelting reaction and thus is distinctly different from the belite in conventional cement, which is rapidly quenched to depress the reaction. The remelted belite has a weaker resistance to fracture than does the quenched material and thus has better grindability. When the two cements, with nearly the same particle‐size distributions, are compared, the specific surface area of the remelted belite cement is higher, resulting in higher hydration activity.
