Fiber reinforced concrete is a composite material made of cement, mortar or concrete with closely spaced fibers added. The fibers, which can include glass, carbon, polypropylene or nylon, increase the tensile strength and crack resistance of the concrete. Fiberglass reinforced concrete (GFRC) specifically uses glass fibers in the mix. It provides an ultra-strong yet flexible concrete that protects against environmental damage. GFRC is lightweight, durable, and can be cast into complex shapes. Some key properties and applications of fiber reinforced concrete include increased tensile strength, impact resistance, limited crack growth, use in pavement overlays, industrial floors, bridges, canal linings, blast resistant structures, and pre

2. WHAT IS FIBRE (FIBRE-REINFORCED) CONCRETE?
• Fiber reinforced concrete is a composite material consisting
of cement paste, mortar or concrete with closely spaced and
uniformly dispersed fibers of polypropylene, nylon, asbestos,
coir, glass and carbon (circular or flat). It is also known as
GFRC or simply FRC.

3. • Fiberglass reinforced concrete (GFRC), is a concrete
mixture that has high strength fiber glass in the mix.
This provides a ultra strong and somewhat flexible
concrete that also protects the concrete from
environmental damage over the years. It is lightweight
and durable and can be cast into many different shapes.
The mix consists of Portland cement, fine aggregate,
glass fiber reinforcement, additives, acrylic co-polymer
and water.

4. PROPERTIES AND APPLICATION OF
FRCProperties:
Fibers introduced in concrete impart the following
properties:
a) Increased static and dynamic tensile strength
b) Improved impact strength
c) Limited crack growth
d) Increased strain capacity

5. Application:
Because of the increased static and dynamic tensile strength,
energy absorbing characteristic and better fatigue strength,
fiber reinforced concrete has been used in:
a) Overlays of air fields, road pavements, industrial floorings
and bridges decks etc.
b)Canal and refractory linings
c) Explosive resistant structures
d)Precast products such as pipes, beams, staircase steps, wall
panels, proof panels and manhole covers etc.

6. ADVANTAGES OF FIBERGLASS REINFORCE
CONCRETE
• It is a great material for restoration of old buildings and is
used for the exterior of the buildings. It is also being used
extensively for walls and ceilings. Landscape artists have
come on board and discovered the versatility of GFRC.
• GFRC is lightweight and is about 75% lighter than traditional
concrete.
• The flexural strength gives it a high strength to weight ratio.
• The reinforcement for this concrete is internal and does not
need additional reinforcements.

7. • Heavy duty or expensive equipment is not necessary
when pouring or spraying GFRC.
• It is easy to cut and is very difficult to crack.
• GFRC is very adaptable in that it can be poured or
sprayed.
• When sprayed, the surface finish has no pits or bug-
holes. If it is poured, it is easily shimmied to remove
all pits and bug-holes prior to hardening

8. DISADVANTAGES OF FIBERGLASS
REINFORCE CONCRETE
• There is no ductility. Ductility is a solid material’s
ability to deform under stress.
• The cost of GFRC is higher than traditional
concrete. Due to the fiberglass being inside the
concrete and the addition of additives and acrylic
co-polymer the price is steeper.

9. • GFRC is difficult to self-mix. Generally, a contractor
will mix and pour or spray this type of concrete.
• While the mix can be pretty versatile it can fall apart if
not properly applied or poured. The use of materials
such as wire along the foundations, walls and ceilings
will help the concrete adhere and have a stronger
finish

10. USES OF FIBERGLASS REINFORCE CONCRETE
• So, while fiberglass reinforced concrete is still relatively new
and its uses have not been fully developed, it is becoming a
popular choice for contractors and landscapers. Its durability
and lightweight design enables it to be used in many different
situations.

11. • While GFRC is excellent for new building exteriors and
restoration projects of the facades of old buildings, it is
also being used out of the box. It is also being used to
construct walls and ceilings within buildings. GFRC is
being used extensively in landscaping and water
features. Due to its ability to be poured in almost any
cast, it is excellent for sculptures as well as
prefabricated rocks and boulders. Landscape artists are
using this material for one-piece waterfalls, landscape
sculptures, boulders, cremation urns and memorial
stones.
