2. Calcium magnesium acetate - Wikipedia

   en.wikipedia.org/wiki/Calcium_magnesium_acetate

   Calcium magnesium acetate (CMA) is a deicer and can be used as an alternative to road salt.It is approximately as corrosive as normal tap water, and in varying concentrations can be effective in stopping road ice from forming down to around −27.5 °C (−17.5 °F) (its eutectic temperature [1]).

3. Deicing - Wikipedia

   en.wikipedia.org/wiki/Deicing

   An Aeroflot Airbus A330 being deiced at Sheremetyevo International Airport Econ Salt Spreader. Deicing is the process of removing snow, ice or frost from a surface. Anti-icing is the application of chemicals that not only deice but also remain on a surface and continue to delay the reformation of ice for a certain period of time, or prevent adhesion of ice to make mechanical removal easier.

4. Sodium acetate - Wikipedia

   en.wikipedia.org/wiki/Sodium_acetate

   A supersaturated solution of sodium acetate in water is supplied with a device to initiate crystallization, a process that releases substantial heat. Solubility from CRC Handbook Sodium acetate trihydrate crystals melt at 58–58.4 °C (136.4–137.1 °F), [ 12 ] [ 13 ] and the liquid sodium acetate dissolves in the released water of ...

5. Trench drain - Wikipedia

   en.wikipedia.org/wiki/Trench_drain

   Suspending the form inside the trough (and flush with the surface elevation), such that there is space (6 inches (150 mm) or more) below and to each side of the form; Attaching the drainage pipes to the suspended form; Filling the trench with concrete (surrounding the form base and sides) and finishing the concrete flush with the metal frame;

6. Potassium acetate - Wikipedia

   en.wikipedia.org/wiki/Potassium_acetate

   Potassium acetate (as a substitute for calcium chloride or magnesium chloride) can be used as a deicer to remove ice or prevent its formation. It offers the advantage of being less aggressive on soils and much less corrosive: [5] for this reason, it is preferred for airport runways although it is more expensive.

7. Hydrodemolition - Wikipedia

   en.wikipedia.org/wiki/Hydrodemolition

   Robotic Hydrodemolition in Folkestone, UK. Hydrodemolition of concrete exposing the rebar.. Hydrodemolition (also known as hydro demolition, hydroblasting, hydro blasting, hydromilling, waterblasting, and waterjetting) is a concrete removal technique which utilizes high-pressure water, often containing an abrasive material, to remove deteriorated and sound concrete as well as asphalt and grout.

8. Waterstop - Wikipedia

   en.wikipedia.org/wiki/Waterstop

   Waterstops are manufactured from a variety of materials depending on the functionality and their intended use. The most common types are: Waterstops made from extruded plastics such as flexible polyvinyl chloride PVC, polyethylene (PE) or thermoplastic vulcanized rubber (TPV); formed metal such as stainless steel, copper, or carbon steel - with or without polymeric coatings; extruded ...

9. Tremie - Wikipedia

   en.wikipedia.org/wiki/Tremie

   The tremie concrete placement method uses a vertical or nearly vertical pipe, through which concrete is placed by gravity feed below water level. [4]The lower end of the pipe is kept immersed in fresh concrete so that concrete rising from the bottom displaces the water above it, thus limiting washing out of the cement content of the fresh concrete at the exposed upper surface.
