In this research, the changes of micropores and the mechanical properties of concrete with mix proportions at water cementitious material ratios between 17% to 33% after centrifugal compaction were compared with those during vibrating compaction to investigate the influence of centrifugal compaction on concrete in such a high strength region. The measurement of micropores was performed by two kinds of methods: air void measurement by linear traverse method and the pore size distribution method. In a mix proportion with water cementitious material ratio between 17% and 23%, the compressive strength and Young's modulus tended to increase in case of centrifugal compaction compared to vibrating compaction. The difference in the condition of micropores of these test specimens in centrifugal compaction and vibrating compaction did not exist in pore size distributions of 0.003 to 30 microns, but the air voids in case of centrifugal compaction tended to be lesser. It was concluded, therefore, that in high strength concrete with water cementitious material ratio between 17% and 23%, air voids between 30 and 1000 microns decreased due to the influence of centrifugal compaction and the strength increased.
