To examine possibility to product particular cement appling control a specific particle character of cement, the study takes samples of OPC, minute particle cement and large particle cement of the progress to product OPC. to make progress a basic experimentation of mortar property. this is the result. fluidity and air content of minute particle cement and large particle cement are similar to OPC mortar, and a setting phenomenon of minute particle cement is faster than any others. n specific character manifesting strength, the primary stage`s compressive strength(16.7MPa) of the first day of minute particle cement is similar to the compressive strength(18.3MPa) of the third day of OPC mortar, and the primary stage`s compressive strength of the first day of the mix of OPC and minute particle cement mortar manifest 11.9MPa. There for, minute particle cement can be alternate instead of high strength cement which is being distributed. However, to apply smoothly according to economical efficiency and request of a site, it is to use the mix of OPC and minute particle cement suitable to ensure a high strength property.
