Summary
Developing new icephobic surfaces is crucial for equipment efficiency and safety. This study introduces a standardized test bench, revealing that low humidity is key to accurately measuring icephobic properties.
Area of Science:
- Materials Science
- Surface Engineering
- Tribology
Background:
- Ice accumulation on equipment poses significant efficiency and safety risks.
- Existing methods for characterizing icephobic surfaces lack standardization, leading to inconsistent results.
- Standardized testing is needed to reliably evaluate and compare icephobic surface performance.
Purpose of the Study:
- To develop a novel, reproducible test bench for characterizing icephobic surfaces.
- To simultaneously measure ice adhesion strength and icing delay time (IDT).
- To investigate the influence of controlled humidity on ice adhesion and IDT.
Main Methods:
- Development of a new, standardized test bench for icephobic surface evaluation.
- Simultaneous measurement of ice adhesion strength and icing delay time (IDT).
- Testing under controlled humidity conditions to assess environmental influences.
Main Results:
- Increasing relative humidity significantly increases ice adhesion strength.
- Higher humidity levels lead to decreased icing delay time (IDT).
- Humidity is a critical factor influencing the measured performance of icephobic surfaces.
Conclusions:
- The developed test bench provides a reproducible method for evaluating icephobic surfaces.
- Testing under low humidity conditions is recommended for accurate assessment of intrinsic icephobicity.
- Understanding and controlling humidity is essential for reliable icephobic surface characterization and development.

01:21Masonry in Cold and Hot Weather Conditions
In cold weather, masonry construction requires specific precautions to ensure mortar does not freeze before curing, as this can significantly weaken its strength and watertightness. Mortar temperature should be maintained between 60°F and 80°F to support proper hydration and curing. Below 40°F, mortar water must be heated, but should not exceed 120°F as high temperatures can reduce mortar's compressive and bond strength.

01:14Testing Water Quality
When the quality of water for concrete preparation is uncertain, its impact on the setting time of cement and compressive strength of mortar is assessed by comparison with de-ionized or distilled water benchmarks. American Society for Testing and Materials (ASTM) C1602 requires the setting times to be within 90 minutes of the control, British Standard (BS) 3146:1980 allows a 30-minute variance in the initial setting, while British Standards European Norm (BS EN) 1008 specifies initial setting...
01:27Cold Weather Concreting
When freshly poured concrete is exposed to freezing temperatures before it has set, the water within the concrete can freeze. This expansion disrupts the setting process, delays chemical reactions necessary for hardening, and increases the volume of pores within the hardened concrete, which weakens its overall structure. If the concrete manages to reach an appreciable strength before it freezes, the damage can be somewhat mitigated.

01:27Frost Action on Concrete
Concrete structures in cold climates, such as those along roadsides, can retain moisture. This moisture makes them susceptible to frost-related damage when temperatures fall below freezing. Adding moisture worsens the damage during temperature fluctuations, leading to repeated freezing and thawing. De-icing salts, spread over these structures to melt ice, add to the freeze-thaw cycle, and draw even more moisture into the concrete.

01:29Frost Resistant Concrete
Concrete's susceptibility to frost damage during freeze-thaw cycles demands strategic measures to enhance its frost resistance. Employing techniques like air entrainment, adjusting the water-cement ratio, proper curing, and selecting appropriate aggregates are essential.
Introducing microscopic air bubbles into the concrete mix through air entrainment creates small voids that accommodate ice expansion, thereby reducing internal pressures and preventing cracking. The optimal amount of entrained...

01:14Design Example: Managing Concrete Workability
This example deals with managing the workability of concrete for a raft foundation project under hot weather conditions. Workability is crucial for ensuring the concrete is easy to place, compact, and finish. In this scenario, a slump test — a common method to measure the workability of fresh concrete — initially indicated low workability. This was attributed to the rapid water loss from the concrete mix, exacerbated by the high temperatures causing the course aggregates to heat up.
