Abstract |
This study experimentally investigated the effect of cross-sectional shape on the compressive strength of concrete with identical width-to-height ratios (). Prismatic and cylindrical specimens were prepared under various curing conditions (standard and field-sealed, under cold weather and under normal weather) and ratios of 1.0, 1.5, and 2.0. The test results showed that both specimen types exhibited nearly identical strength development, with differences within 5 %. At a ratio of 2.0, cylindrical specimens showed slightly higher compressive strength than prismatic specimens. These findings indicate that prismatic specimens produced using detachable formwork during actual placement can effectively represent the in-situ quality of cast concrete and are therefore suitable for practical field quality control applications.
