The fracture properties of engineered cementitious composites (ECC) exposed to dry-wet cycles in sulfate and sulfate-chloride solutions were studied by three-point bending (TPB) beams at the corrosion periods 0, 30, 90, 130, 180, 270, 360 days. digital image correlation (DIC) technique was used understand whole process. toughness energy calculated using proposed method, evolution horizontal strain field, displacement process zone (FPZ) investigated. Meanwhile, compressive tensile performance specimens same analyzed. results showed that (1) Compared water immersion, environments beneficial improving strength, weakening ductility. (2) With increasing time, unstable can be distinguished into three phases: a stable phase, an rapidly decreasing initial followed then trend. initially decreased tended stabilize after 130 (3) By DIC technology, as time increased, opening notch tip trend stabilized 90 days generally. path determined through well matched with macrocrack trajectory. (4) addition chloride ions helped improve mechanical ECC under long-term corrosion, such toughness, energy, tip. Compare concrete, exhibited greater resistance corrosion.
