shortcreting is define as pneumatically applied concrete or motor placed directly on to the surface. Shortcreting can be placed by either the dry mix or wet mix process.

Dry mix process consist of :-

1) Thoroughly mixing the dry material.

2) Feeding of these material into mechanical feeder or gun.

3) Carrying the material by compress air through a nose to special nozzle.

4) Introducing water at nozzle point and immediately mixing it with other ingredient at the nozzle.

5) Jetting the mixture from the nozzle at high velocity on to the surface to receive the shortcrete.

Wet mix process shall be consist of :-

1) Thoroughly mixing all ingredient with the expecting of the accelerating admixture if used.

2) Feeding the mixture into the delivery equipment.

3) Delivering the mixture by positive displacement or compressed air to nozzle.

4) Setting the mixture from the nozzle at high velocity on the surface to receive the shortcrete.

If specification fibre at steel polypropylene or other material as may be specified could also be used together with the admixture to modify the structural properties at the concrete motor being placed in position.
