This could be attributed to the decrease in atom distance at low temperatures, the increase in the attractive force between atoms [ 28 ], and the change in fiber performance at low temperatures [ 51 ]. For dry specimens, there is a temperature point between −20~−60 °C, which causes the specimens to change from ductile to a quasi-brittle fracture.…”

This research will help to improve our understanding of the fracture properties of ECC at low temperatures (long-term low temperatures, freeze–thaw) and evaluate the safety properties of ECC under low-temperature conditions. Three levels of saturation (saturated, semi-saturated, and dry), four target temperatures (20, 0, −20, and −60 °C), and the effect of the coupled of the two on the mode I fracture properties of ECC were investigated. Then, we compared and analyzed the fracture properties of ECC loaded at 20 and −20 °C, after different freeze–thaw cycles (25, 50, 100 cycles), which were compared with saturated specimens without freeze–thaw at the four target temperatures to analyze the differences in low-temperature and freeze–thaw failure mechanisms. Temperatures and saturation have a significant effect on the fracture properties. Low temperatures and freeze–thaw treatments both decreased the nominal fracture energy of ECC. Distinct differences in matrix and fiber-matrix interface damage mechanisms have been discovered. Low temperatures treatment transforms ECC from a ductile to a brittle fracture mode. However, even after 100 freeze–thaw cycles, it remains ductile fractured. This study complements the deficiencies of ECC in low-temperature theoretical and experimental applications, and it sets the stage for a broad range of ECC applications.

“…Other research (Lu et al, 2017;Qiao et al, 2015) has also looked at the effects of fatigue loading, freeze-thaw exposure, and both fatigue loads and freezing-thawing on the concrete and its strength. Lu et al (2017) found that exposing concrete to freezing and thawing before fatigue loading made the concrete much weaker than if it first underwent fatigue loading and then was exposed to freezing and thawing.…”

In areas with cold winters, premature failure in concrete pavement joints is a frequent phenomenon, yet there is no standard test method for evaluating their durability. In this study, the effectiveness of several evaluation techniques for concrete joint durability were evaluated. Concrete slabs with saw cuts representing joints were made, and exposed to different freezing and thawing/ wetting cycles, and different salt solutions (NaCl, CaCl2, and MgCl2). The durability of the joints was evaluated using measures of strength loss, mass loss, and a visual inspection. It was found that under these exposure conditions, the strength loss and visual inspection modes of evaluation could discern different levels of damage between different types of exposures, and also different concrete mixes (e.g. Different cement contents, strength and the presence or absence of SCM). Further research is required to evaluate the effects of sealants, saturated bases, and higher salt concentrations.

“…However, few works in the literature have focused on one quantification method of damage in concrete under fatigue loading by using AE for characterizing the entire three deterioration behaviors simultaneously. Specifically, most contributions only considered the experimental investigations on the empirical relationship between a single deterioration behavior and a certain AE parameter [13][14][15][16][17][18][19]. For instance, Wang et al [15] conducted the comparison on the fatigue properties among plain concrete, rubberized concrete, and polypropylene fiber-reinforced rubberized concrete by applying AE, and the results showed a linear correlation between the AE counts and the residual strain for plain and rubberized concrete, respectively.…”

“…Note that this work only focuses on the damage and AE responses of the concrete materials (i.e., the representative volume elements (RVEs)) due to the sophisticated behaviors under fatigue loading, although a number of works have been contributed by researchers concerning that of reinforced concrete structures. Considering that the materials' behaviors are essential for further analysis of the mechanical behaviors of structures, a great number of studies have been already conducted in the literature [14,15,17,19,28,29,31,42,43]. In addition, the damages of concrete structures subjected to mode-I, mode-II, and mixing mode loading were classified by using AE [3].…”

Acoustic emission (AE) is an effective nondestructive evaluation method for assessing damage in materials; however, few works in the literature have focused on one quantification method of damage in concrete under fatigue loading by using AE for characterizing the entire three main deterioration behaviors simultaneously. These deterioration behaviors include Young’s modulus degradation, fatigue total strain, and residual strain development. In this work, an AE quantification method of fatigue damage in concrete was developed, by combining AE and a fiber bundle-based statistical damage model (fiber bundle-irreversible chain model). By establishing a relationship between normalized AE counts and the damage variable based on the fiber bundle-irreversible chain model, the method was proposed. Additionally, this method was verified against the experimental results. It is able to capture the mechanisms of damage accumulation and characterize the three deterioration behaviors simultaneously.
