Carrot-shaped Sample Testing of Shotcrete
Contents [show]
The slab of concrete (see picture 1) was brought from the construction site. This sample of concrete was used in a tunnel in Attiki Odos. The machine has a rotating pivot. Along with the pressure and the water "cuts" the slab pieces of concrete into carrot-shaped ones.Then, the samples are taken to the machine (see picture 3) in order to be pressed. The values of pressure in which the samples crack, the quality of the concrete used is checked.
