In an era of continued economic development around the globe, numerous rock-related projects including mining and gas/oil exploration are undertaken in regions with cold climates. Winters in the Iranian western and northwestern provinces are characterized by a high precipitation rate and a cold weather. Under such conditions, rocks are exposed to long freezing periods and several freeze-thaw (F...

A study of the weathering process three types stones, sandstone, marble, and granite, which are commonly found in artifacts worldwide, is presented. Freeze–thaw cycles used to accelerate changes stone’s physical properties, such as surface morphology, mass, porosity. Pulsed infrared thermography, an situ non-destructive testing method, adopted measure thermal diffusivity, effusivity, conductivi...

Compared with plain soil, polypropylene (PP) fiber-reinforced soil has markedly improved mechanical properties and can be used in slope protection projects. To investigate the reduction law of antierosion ability parameters PP loess under dry-wet (D-W) cycles freeze-thaw (F-T) cycles, we took from Yan’an, China, mixed them fiber, did shear strength tests, disintegration permeability tests D-W F...

Abstract Freeze-thaw cycles exert an important abiotic stress on plants at the beginning of winter and spring in mid-to-high latitudes. Here, we investigate whether effects freeze-thaw are carried over into growing season wetlands. We conduct a temperature-controlled experiment under two flooding conditions typical plant ( Scirpus planiculmis ) soil from Momoge wetland (China) analyze microbial...

Freeze–thaw resistance is a significant issue in the durability of concrete; however, it not widely discussed context limestone addition to concrete. The present study aims compare effect different types powder on frost ordinary and self-compacting Three were added concrete an amount 15% 30% cement weight. Compositions with without air-entraining admixture prepared each instance. Research inclu...

Freeze–thaw cycles and steel reinforcement corrosion can damage the properties of concrete structures in a frigid marine environment. In this paper, experimental analytical research on freeze–thaw resistance recycled coarse aggregate (RAC) bond performance corroded RAC after was conducted. The results showed that ultimate strength decreases with increasing rates, more rapidly under coupled effe...

Abstract To explore how to respond seasonal freeze–thaw cycles on forest ecosystems in the context of climate change through thinning, we assessed potential impact thinning intensity carbon cycle dynamics. By varying number temperature cycles, effects various intensities four seasons. The rate mass, litter organic carbon, and soil (SOC) loss response variations was examined two degrees decompos...
