Which is better shotcrete or gunite?

Gunite generally lasts longer and maintains a higher quality than shotcrete. For instance, gunite tends to dry faster than shotcrete, leading to a much smoother surface and avoiding significant cracks from shrinking. Gunite can also withstand up to 9500 psi, a much higher psi than shotcrete.

What is a shotcrete retaining wall?

Shotcrete retaining walls comprise a special mix of high strength concrete being sprayed at high velocity using compressed air, to form a retaining structure, drain or a wall.

What is difference between Guniting and grouting?

Suspension grout is a mixture of one or several inert materials like cement, clays etc suspended in a fluid i.e water. Suspension grout is a mixture of pure cement with water. Liquid grout or solution grout consists of chemical products in a solution or an emulsion form and their reagents.

Are shotcrete and gunite the same thing?

Gunite Types: Dry Shotcrete or Wet Shotcrete Gunite and shortcrete are essentially the same material, but they are applied with different processes. Gunite is the popular trade term for dry-gun concrete, while shotcrete is the common term for wet-gun concrete.

What’s the difference between dry shotcrete and gunite?

The Guniting process is also known as Dry Shotcreting. It is a process of spraying a mix of mortar or concrete at high pressure to the surface with the help of spray gun. Guniting is one of the most effective techniques which is widely used for the repairing of the concrete which is damaged.

What is the use of guniting in construction?

What is Guniting? Guniting is a process used in construction for the application of slope stabilization and certain rehabilitation purpose mainly in the construction of retaining walls, swimming pool construction, tunnel construction, in fluid tank construction and some of the concrete repair works.

Which is the best way to apply shotcrete?

Shotcreting is the best method in which the concrete mix is applied in layers under the pressure of compressed air. The water cement ratio for shotcrete normally ranges within 35 to 0.50 by mass which is somewhat lower than for most conventional concrete mixes.

What kind of cement mix do you use for guniting?

5. The mix proportion used for guniting are 1:3 and 1:4:5. This will generally have a water cement ratio of 0.30. A 1:3 mix will attain a strength of 70MPa in the 7 th day after application. 6. The size of fine aggregate used in the mix is 10mm. 7.
