Carbon Nanotubes and Resistance to Freeze-Thaw Cycles

Freeze-Thaw Resistance of Concretes with BFSA

Abstract—Air-cooled Blast Furnace Slag Aggregate (BFSA) is usually referred to as a material providing for unique properties of concrete. On the other hand, negative influences are also presented in many aspects. The freeze-thaw resistance of concrete is dependent on many factors, including regional specifics and when a concrete mix is specified it is still difficult to tell its exact freeze-th...

Simulating Martian Conditions: Methanogen Survivability during Freeze-thaw Cycles

Introduction: Methanogens are obligate anaerobes that use molecular hydrogen as an energy source and carbon dioxide as a carbon source to produce methane. They are classified as Archaea and are found in many extreme environments, including hydrothermal vents, volcanoes, and also the human microflora. The current Martian atmosphere is low in pressure, very dry (hyper-arid), and high in radiation...

Acoustic Emission to Detect Damage in FRP Strength Under Freeze and Thaw Cycles

Intraspecific variation in response to magnitude and frequency of freeze-thaw cycles in a temperate grass

Winter warming and its accompanying predicted decrease in snow pack for northern temperate regions may increase frost damage to plants induced by an increase in freeze-thaw cycles (FTCs) due to reduced insulation. FTC frequency, minimum temperature during freezing and pre-existing local adaptations potentially all influence site-specific plant responses to future climatic changes. Within a cham...
