WHY
A SILO MANUFACTURER WOULD LIKE TO INTRODUCE YOU TO GUNNITE
(SHOTCRETE) ?
When
travelling through countryside you can see from time to
time a silo "dripping".The liquid coming out the
wall of that structure is silage acids that deteriorates
concrete and steel.That liquid is produced when the moisture
content of the ensiled material is too high for the size
of the silo (the bigger the silo, the lower the moisture
content of the material to be respected to avoid seepage).
The rate and severity of the degradation of the concrete
wall will depend on different factors, one of, which is
the frequency at which the silo was filled with too moist
silage. Restoration of silo walls with gunnite is the stronger,
safer, long lasting and economical way to repair and save
your initial investment.
DEFINITION
OF GUNNITE:
"Gunnite
is a process where concrete is projected under pressure
onto a surface to form structural shapes such as walls and
roofs"-PCA
GUNNITE
VS CONVENTIONAL CONCRETE:
Conventional
concrete is placed first and than vibrated; while gunnite
is placed and compacted at the same time. This is a possible
due to the tremendous force with which it is projected from
the machine. Because of this process the end product offers
better quality such as higher density, reduced permeability,
increased compressive strenght and resistance to chemical
attacks. With the proper preparation of the surface to be
repaired and the force of application of the product, the
bond between the surfaces is higher than the material of
the old surface.
The
use of Gunnite has been widely spread of successfull restorations
of old silo walls for over 25 years.Thus, gunnite is an
efficient solution to a real problem.
OTHER
USE OF GUNNITE:
Gunnite
is used to restored bridges, water dams, overhead parking
garages, tanks, pools, tunelling...
