What is shotcrete and when is it used?

Shotcrete is applied using a wet- or dry-mix process. The wet-mix shotcrete process mixes all ingredients, including water, before introduction into the delivery hose. The dry-mix shotcrete process adds water to the mix at the nozzle. Shotcrete is used in new construction and repairs and is suitable for curved and thin elements (ACI 506R).

2020-1-23  Batching and mixing a high-quality and pumpable wet-mix shotcrete is not always a simple task, particularly when high dosages of fibers are used. Using a classic mix design approach for conven-tional concrete may result in non-pumpable or difficult to pump concretes. Adding fibers to ordinary wet-mix shotcrete can produce similar effects.

What Is The Difference Between Concrete Vs. Shotcrete

2021-8-19  One widely used speciality concrete is known as “shotcrete.”. The major difference between shotcrete and its close cousin, concrete, is the placement method. Concrete is discharged from a ready-mix truck, placed on the ground or in forms and then must be vibrated for compaction. By contrast, the shotcrete process, whether using wet or dry ...
