Abstract:
The vehicle in the classical method to spray shotcrete is compressed air. Thereby the aggregate and the cement are transported within a high speed stream of air in the state of a suspension. Many attempts have been exerted to apply other possiblities of transporting the concrete mix. Despite of these numerous efforts there basically remain three varioes methods: 1 dry aggregate suspended in a stream of air 2 slugs of wet mix propelled by compressed air 3 compact wet mix pressed forward mechanically. I will refer to hereafter as method one, two and three.
