| 要旨 |
The effect of size of specimens on freeze-thaw deterioration of concrete was studied. Three different mixes with varying water-cement ratios and air content were used to cast prismatic specimens of three different sizes. Mold -gauges were cast inside one specimen of each size for one mix to measure the variation of strain. Also, thermocouples were cast within the specimens to study the variation of temperature at various locations. The temperature gradient generated within the specimens and the variations of strain with temperature gradient generated within the specimens and the variation of strain with temperature under rapid freeze-thaw conditions have been presented.
