Antifreeze Admixtures for Concrete during Cold Weather
The antifreeze admixtures are technologically simple and beneficial for cold weather concreting. The admixture helps in improving the cohesiveness, cold joint minimizations, sand streaking, and plasticity. These are estimated to provide large cost saving than other methods of steam curing or concrete enclosures.
Antifreezing and Stretchable Organohydrogels as Soft
First of all, a polyacrylamide (PAAm) organohydrogel with a glycerol-water binary solvent was prepared; the strong hydrogen-bonding interactions between glycerol and water molecules not only prevent the organohydrogel from freezing at low temperature but also hinder water molecules from evaporating in air, giving the gel a long-term durability.
Tough, anti-freezing and conductive ionic hydrogels | NPG
At 50 wt% KAc, the hydrogels also exhibited the best antifreezing performance, remaining unfrozen at temperatures below 60 °C. They also showed a high conductivity of 8.0 S/m at room temperature...
- What type of antifreeze is used in electronics cooling?
- The most common water-based antifreeze solutions used in electronics cooling are mixtures of water and either ethylene glycol (EGW) or propylene glycol (PGW). The use of ethylene glycol has a longer history, especially in the automotive industry.
- Why are low molecular weight organic compounds a good antifreeze agent?
- Low molecular weight organic compounds tend to have melting points lower than water, which makes them suitable for use as antifreeze agents. Solutions of organic compounds, especially alcohols, in water are effective.
- What is the purpose of antifreeze?
- The purpose of antifreeze is to prevent a rigid enclosure from bursting due to expansion when water freezes. Commercially, both the additive (pure concentrate) and the mixture (diluted solution) are called antifreeze, depending on the context.
- How is antifreeze made?
- Most antifreeze is made by mixing distilled water with additives and a base product, usually MEG (mono ethylene glycol) or MPG (mono propylene glycol).
- What is a good solution for antifreeze?
- Solutions of organic compounds, especially alcohols, in water are effective. Alcohols such as methanol, ethanol, ethylene glycol, etc. have been the basis of all antifreezes since they were commercialized in the 1920s.
- Is glycerol a good antifreeze?
- Glycerol was historically used as an antifreeze for automotive applications before being replaced by ethylene glycol. Volkswagen introduced G13 (TL 774-G) antifreezes containing glycerol in 2008, marketed as better for the environment due to its low toxicity and reduced CO 2 emissions.
