This study discusses the influence of fineness of cement on mechanical properties of cement mortar. According to the result, compressive strength increases in order of C>B>OPC>A and C>B>A>OPC at mixture proportion of 1:1 and 1:3 respectively. An increase of compressive strength by increase of fineness of cement is because internal structure of concrete grows dense by an increase of hydration reaction. As for curing condition, compressive strength is higher in standard curing than in air curing at mixture proportion of 1:1 and 1:3. There is not any tendency of strength development with age and fineness of cement by 91days. Length change by drying shrinkage increases in order of C>B>OPC>A at mixture proportion of 1:1 and 1:3 due to an increase of water content by variation of W/C.
