“…A sudden heat shock will greatly affect a building's reliability and life. The freeze-thaw damage is the main reason of the failure of a cement-based material [21][22][23][24][25][26][27][28][29]. If the thermal response to the environment temperature change is slow and the inner temperature will not change much with 12 hours, such freeze-thaw damage can be avoided by covering a porous coating with a structure similar to the cocoon wall.…”

A building or a bridge might collapse after a heat shock. This paper shows that a porous hierarchy of a coating can effectively prevent a building or a bridge from such damage. A cocoon’s geometrical structure is studied and its resistance to the heat shock is revealed by a thermal oscillator. The theoretical model reveals an extremely low frequency of the thermal oscillator, which is very important for cocoons’ biomechanism, especially in the heat insulation function. At the same time, it shows that the cocoons have the best thickness to protect the pupa from the environment. In addition, surface temperature measurement of hierarchical mulberry leaves is performed. This work provides new insights into biomimetic design of the protective building and coatings.

“…In addition to the thermal stresses developed due to the thermal mismatch between the ice layer and concrete surface described by the glue spalling [9], more the minimum temperature is decreased, finer pores (in the order of one nanometer) near the surface will be frozen too. According to the Gibbs-Thomson equation used in [5], which links the freezing temperature to the threshold radius of frozen sites, at -5 °C the pores that freeze are of the order of 14 nm in radius. As the temperature decreases, ice crystals grow in finer pores: at -20 °C, the pore radius is about 4 nm, then about 4 times finer than the pores that freeze at -5 °C.…”

“…As for internal damage, a severe deterioration is induced under the effects of hydraulic [1], osmotic [2] and crystallization [3,4] pressures accompanying water phase change and ice formation inside the porosity. The pressures' theories and models explain how this above combination leads to the internal damage mechanisms of concrete [5]. The role of the entrained air voids as expansion valves is also understood in these theories.…”

Testing methods for freeze-thaw scaling of concrete in presence of de-icing salts are developed in the form of normative documents to assess the frost resistance of concrete, aiming to unify the testing standards. These tests consist of exposing cured concrete specimens to several freeze-thaw cycles inside a climatic chamber. The amplitude of each cycle may reach 40 °C with considerable freezing and thawing rates that may reach 10 °C/h, depending on the temporal cycle length (24 h vs. 12 h). When comparing different testing methods, it appears that the imposed experimental conditions are significantly different and may lead to conflicting results on a same concrete mix. Moreover, there is a lack of agreement between the test methods and the real environmental conditions. Yet, the assessment of the representativeness of a testing method for freeze-thaw durability should start with the measurement of the concrete response to its natural environment and comparison to its response under laboratory conditions. Therefore, a

“…Mixtures of cement and micro-silica achieve superior performance compared to cement or micro-silica alone. Rhardane et al adopted the numerical methodology at the microscale to quantify the freezing–thawing damage mechanisms on cementitious materials [ 16 ]. They found that the most harmful factors are supercooling and delayed ice nucleation, and the water-to-cement ratio and minimum temperature during freezing–thawing cycles also contribute to material deterioration, but air entrainment can reduce the damage.…”

The skeleton dense graded cement-stabilized crushed stone base is a widely used material for road construction. However, this material is susceptible to freeze–thaw damage, which can lead to degradation and failure, for which there is still a lack of an in-depth understanding of the freeze–thaw damage characteristics. This study aims to assess the mechanical performance and the freeze–thaw damage characteristics of the cement-stabilized crushed stone base with skeleton dense gradation based on a mechanical test and acoustic technology in a laboratory. There is a gradually increasing trend in the mass loss rate of the base material with an increase in freeze–thaw cycles. The curve steepens significantly after 15 cycles, following a parabola-fitting pattern relationship. The compressive strength of the cement-stabilized crushed stone base also decreased with a parabola-fitting pattern, and the decrease rate may accelerate as the freeze–thaw cycles increase. The resilience modulus of the base material decreased with increasing freeze–thaw cycles, following a parabolic trend. This suggests that the material’s resistance to freeze–thaw damage decreases with increasing cycles. The ultrasonic wave velocity decreased with increasing freeze–thaw cycles, exhibiting a parabolic trend. This decline can be attributed to microcracks and defects developing within the material, offering insights for monitoring and predicting its service life. The damage progression of the cement-stabilized crushed stone base was found to occur in three stages: initial, stationary, and failure. The duration of stage I increased with freeze–thaw cycles, while the duration of stage III decreased. The findings provide valuable insights into the mechanisms and processes of freeze–thaw damage in a cement-stabilized crushed stone base with skeleton dense gradation.
