This study describes an experimental study on the strength characteristics of fiber-reinforced concretes (FRC) under the two different seawater exposure conditions such as constant-soaking and soaking and dry conditions in every two days for curing of FRC specimen. For this study, steel, aramid and carbon fibers were mixed with 1.0% of the constant fiber volume fraction of concrete. From the test results, it seems that compressive strength and splitting tensile strength of FRC were not much affected by seawater exposure conditions for 14, 28 and 56 days. Also it was observed the stress-strain relationship of FRC was not affected by the seawater exposure conditions. However, the strength ratio between splitting tensile strength and compressive strength of FRC exposed to seawater showed a slightly higher than those of other researches. |
