“…The size of the fracture process zone is represented by a material property called the characteristic length, l ch . It expresses the fracture properties of the concrete, such as the modulus of elasticity, E c , the fracture energy, G f and the tensile strength, f ct , where f ct is the direct tensile strength of concrete as determined by the direct tension test [48] or any other fracture mechanics test:…”

“…The experimental research on triaxial compression strength and deformation of plain concrete under F-T cycles was carried out (Jin et al 2013). The tension characteristics of high-strength concrete after F-T actions were investigated (Marzouk et al, 1994). The F-T durability of cellular concrete was studied (Tikalsky et al 2004).…”

The evolution and spatial distribution of internal random pore structure are key factors in damage mechanism and macro-mechanical properties of concrete material under freeze-thaw (F-T) environment. This paper was presented to discover the deterioration mechanism of concrete under F-T actions. Through the experiment, visual examination was employed to evaluate the surface damage; the degradation considering the mass loss and uniaxial compressive strength of concrete was statistically analyzed under F-T environment. Moreover, X-ray tomography was adopted to characterize the concrete internal structure subjected to F-T cycles. The specimens exposed to F-T environment were scanned at regular intervals. Coupled with CT test, the pore space was characterized in terms of porosity and pore distribution by image analysis. And the relationship between the pore structure and the F-T cycles was described quantitatively by the fractal theory. The results indicated that the fractal dimension of the pore structure presented "down-up" trend with the number of F-T cycles increasing. The pore structure evolution changed from chaos to order and then to a process of disorder. The results demonstrated that F-T cycles accelerated the generation of meso-damage in concrete, which leads to more severe damage under F-T cycles.

“…Two main methods are generally used to explore the fracture energy of cement-based materials, the threepoint bending test [13][14][15] and direct or uniaxial tension test [11,16]. Although the uniaxial tension test setup is more difficult to perform, it is more suitable for investigating the fracture energy under quasi-static condition and increased strain rates since the complete stress-deformation curve is measured directly.…”
