 note = {In this study, for the purpose of rationalization and labor saving of compressive strength test of concrete,we suggest φ75 mm specimen. So, it was examined whether cylindrical specimen of φ75 mm can be used as a specimen for concrete compressive strength test, and compared with φ100 mm specimen. As a result,the compressive strength of φ75 mm specimen was about the same strength as the φ100 mm specimen,when the sealed curing and the underwater curing were carried out. The coefficient of variation of φ75 mm specimen was about 5%. Therefore, it is considered that φ75 mm specimen can be used as management specimen for standard underwater curing and on-site sealed curing specimen., 本研究では，コンクリートの圧縮強度試験の合理化および省力化を目的とし，JIS A 1132 に規定されている供試体の直径は粗骨材最大寸法の3 倍以上という条件を重視した．そして，φ75mm の円柱供試体がコンクリート圧縮強度試験用供試体として活用できるかどうか，従来のφ100mm の円柱供試体の圧縮強度，圧縮強度の変動係数および見掛け密度を，気中養生，封かん養生および水中養生を行った場合について比較検討した．},
