Advantages:
It is very useful and has great advantages over conventional
concrete in a new variety of construction and repair works.
1. Excellent bonding in nature makes the concrete layers
very strong.
2. It is more economical than conventional concrete and
requires less formwork.
3. The Concrete can be applied by a nozzle from a safe
distance.
Disadvantages:
1. The production cost is very high.
2. Dusting problems.
3. So many wastages of concrete.
Applications:
1. Thin overhead vertical or horizontal surfaces.
2. Curved or folded sections like tunnels, canals,
reservoirs, or swimming pools, and pre-stressed tanks.
