چکیده انگلیسی
Interactive effects of freeze-thaw cycle and carbonation on ECO-HDCC tensile property were studied. Loading regime, interaction cycle and preloading level of ECO-HDCC were considered. Also, carbonation front was determined using thermal analysis and X-ray diffraction methods. Results indicate that monotonic and cyclic loading regimes create minor differences in tensile performance of ECO-HDCC. Tensile stress of ECO-HDCC increases for 1-5 interaction cycles while decreases for 10-15 interaction cycles. Tensile strain of ECO-HDCC decreases as the interaction cycle increases. In addition, strain preloading level with a range of 0.6% has little influence on tensile property for ECO-HDCC. Results also revealed that carbonation fronts of ECO-HDCC are 3 mm and 7 mm for 1 and 3 interaction cycles, respectively. Finally, after interactions of 15 cycles, tensile property of ECO-HDCC with un-preloading under monotonic loading regime is selected for bridge deck link slab design.
