Information on GFRC to be formated

Glass Fiber Reinforced Concrete, GFRC
»GFRC has superior fire retardant properties.
»GFRC is lightweight
»GFRC can replicate granite,
limestone, cast stone or other hard to use
materials
Composition – GFRC is composed of:
»»Concrete- Portland cement
»»Aggregates – Selected crushed stone or
silica sand
»»Glass Fibers- to provide tensile and flexural
strength
»»Polymers- to improve toughness
GFRC can be used wherever a light, strong,
weather resistant, attractive and fire retardant
material is required.
GFRC can be used as wall panels, window
surrounds, spandrels, column covers, soffits,
cornices, brackets, quoins, railings, pilasters,
copings, domes, etc. Landscape and hardscape
uses include site furnishings, planters,
bollards, urns, tables and fountains.
GFRC is used in historical restorations and
renovations,
bus shelters, security barriers, noise barriers,
marine structures, cable ducts, floating pontoons,
sun screens and storage tanks.
GFRC allows the designer the freedom to
design with less restrictions and weight than
most other materials.
GFRC will
normally weigh between 5 to 25 pounds per
square foot.
3-4 times higher tensile strength than
steel
»»High modulus (in other words not
stretchy, 10 times that of polypropylene.
Low modulus fibers on the other hand,
stretch and allow concrete to crack).
»»Will never rust and so does not require a
minimum cover
»»Inorganic with no health risk
»»Non combustible, so it will not burn
Its installation is quick and relatively
easy.
GFRC can be cast to virtually any shape.
We supply GFRC wall panels, GFRC columns,
GFRC Bas Relief, GFRC domes, GFRC capitals,
GFRC fireplace surrounds, GFRC moldings,
GFRC medallions and all types of custom
GFRC shapes.
Finish- GFRC is available either with a cast in
integral color and texture: limestone, precast,
acid wash, etc. or as paint grade that is easily
finished with virtually any paint.
The strength of GFRC is determined by glass
content, fiber size, fiber compaction, distribution
and orientation as well as degree of cure.
?In the shop drawing phase, GFRC (glass fiber reinforced
concrete) piece length, depth, width, thickness,
squareness, bowing, warpage and locations of
openings or block outs is addressed.
?GFRC is primarily composed of four raw materials:
high density Concrete, glass fiber reinforcement,
aggregate and polymer.
??GFRC products are custom made thin shell
shapes and forms manufactured in a plant by
either one of two methods, both of which center
around how the glass fiber reinforcement is introduced
into the product. One method, known as
the hand lay-up method, simply means that once
the molds have been made and are ready, various
layers of continuous glass fiber mat and Concrete
are manually placed during the “lay-up”
process. Another method, the “chopped-strandspray”
method, introduces glass fiber strands into
the concrete mix as it is being sprayed into the
mold. Both methods
GFRC products are made in molds which
are customized for a particular job or from the
manufacturer’s standard line of molds. Molds
should be manufactured in a manner so as not to
adversely affect the finished product with respect
to shape and finish. The molds should be fabricated
to exact dimension and shape specified by
approved shop drawings.
After the GFRC has set, the glass fiber reinforced
concrete product is carefully removed
from the mold, finished, cured and stored until
adequately cured for shipment.
All glass fiber reinforced concrete manufacturers’
tolerances should be expressed in fractions
of an inch or metric equivalent.
Here are some design considerations
that may affect the cost of GFRC used in
your project:
The amount of detail.
Number of repetitive pieces of glass fiber reinforced
concrete. Numerous casts of a GFRC
shape are more economical per piece, than onetime-
only casts.
Size.
Surface Finish.
Special Reinforcements.
A properly designed, manufactured and installed
GFRC system will provide an innovative
and aesthetically pleasing appearance, while
often reducing overall cost, onsite labor requirements
and shortening construction schedules.
Glass fiber reinforced concrete (GFRC) offers
an endless variety of decorative and ornamental
shapes and forms at affordable prices.
