Abstract
In this study, the bleeding tests were performed to investigate the effects of cement paste(w/c=0.42) on bleeding through varying the number of strand and the diameter of cylinder. The test variables were specified by differing the diameter of cylinder and the number of strand. The bleeding test was performed with respect to all diameter parameters by with or without strand. In addition, the number of strands were specified at four levels, 0, 1, 2, and 3 EA in case of 50 mm cylinder. In case of without strand, the bleeding rate was determined at low level under 2%. Moreover, all of the specimens had similar value in the measurement error. In case of with strand, maximum bleeding rate was 10%. As the diameter of cylinder decreased, the bleeding rate was decreased. The bleeding rate was altered rapidly in between 50 to 100mm of diameter. Even though bleeding rate was increased according to the increase in the number of strand, these tendency for bleeding rate was negligible with the measurement error.
