“…The action of FTCs is one of the causes of the damage to and failure of building structures [2,3]. Currently, the problem of freeze-thaw damage has been studied more vigorously by scholars, and a great deal of research has been conducted on the effects of freeze-thaw damage on the mechanical properties and microstructural variation patterns of cement-based materials; remarkable results have been achieved in these previous studies [4][5][6][7][8][9][10][11]. Among them, hydrostatic pressure theory, osmotic pressure theory, and crystallization pressure theory have high recognition and influence [12,13].…”

Two different freeze-thaw cycles (FTC) are considered in this study to assess the related impact on gas permeability and micro-pore structure of a mortar. These are the water-freezing/water-thawing (WF-WT) and the air-freezing/air-thawing (AF-AT) cycles. The problem is addressed experimentally through an advanced nuclear magnetic resonance (NMR) technique able to provide meaningful information on the relationships among gas permeability, pore structure, mechanical properties, and the number of cycles. It is shown that the mortar gas permeability increases with the number of FTCs, the increase factor being 20 and 12.83 after 40 cycles for the WF-WT and AF-AT, respectively. The results also confirm that gas permeability hysteresis phenomena occur during the confining pressure loading and unloading process.

“…Jacobsen et al [6] investigated the effect of internal cracking on ice formation for high strength concrete. Marzouk and Jiang [7] investigated the tension properties of high strength concrete after freezing and thawing cycles. Miao et al [8] and Sun et al [9] reported that the deterioration of concrete could be accelerated when subjected to dual-damaging processes, e.g., simultaneously subjected to both external loading and freeze-thaw cycles.…”

Using the static and dynamic triaxial experimental machine, experimental study of the strength of wet-screened aggregate concrete are carried out under biaxial compression stress ratios, 0.25, 0.5, 0.75 and 1 after 0, 50, 100, 150, 200, 250, 300 cycles of freeze-thaw. The change of surface of wet-screened aggregate concrete specimens after different cycles of freeze-thaw are observed and described. The failure characteristic of specimens and the direction of the cracks are also observed. Based on the test data, the influence of freeze-thaw cycles and compressive stress ratio on the ultimate compressive strength and corresponding stress-strain relationship is analyzed respectively. The relationships between the ultimate compressive strength and freeze-thaw cycles, the stress ratios are given, respectively. On this basis, the unified failure criterion with consideration of the influence of freeze-thaw cycles and stress ratio is proposed. It can serve as a reference for the maintenance, design and the life prediction of ocean structures, hydraulic structures, marine structures and offshore platform in cold regions.
