kuivasekoitusruiskubetonointi
Kuivasekoitusruiskubetonointi, often referred to by its Finnish name, is a method of applying concrete in which the dry components of concrete are mixed with water at the nozzle just before spraying. This technique differs from wet-mix shotcreting where the concrete is fully mixed before being transported to the nozzle. In the dry-mix process, cement, aggregates, and additives are pre-mixed in dry form and then conveyed through a hose to the spraying nozzle. At the nozzle, water is introduced under pressure, and the mixing occurs as the material is propelled at high velocity onto the surface.
The primary advantage of kuivasekoitusruiskubetonointi lies in its simplicity and the ability to control the water-cement
