The effect of viscosity on the value of fine-grained concrete rebound during spraying concrete is studied. There was used the physical modeling of the spray particles. As an equivalent material there was used polystyrene foam, as a material barrier – shotcrete. Spray particles was carried out using a pneumatic installation. The dependences of the variation in the absorption of energy by spraying the particles of filler on the thickness of the solution at different water-cement ratio are determined. The magnitude of the losses of the mixture at rebound, as well as the penetration depth of particles in dependence on water-cement ratio is determined.
