Fiber Reinforced Concrete (FRC) with Plastic Fibers

This presentation explores Fiber Reinforced Concrete (FRC), emphasizing the use of plastic fibers to enhance PCC (Plain Cement Concrete). It discusses types of fibers, advantages, methodology, testing, and environmental benefits of using plastic fibers in construction. FRC improves durability, crack resistance, and sustainability, making it a cost-effective alternative to RCC (Reinforced Cement Concrete) in suitable applications.

Perfect for civil engineers, construction professionals, and students looking to understand modern concrete technologies

3. What is concrete ?
Concrete is one of the most commonly used building materials. Concrete is a
mixture of cement, water, and aggregates like sand and gravel.

(cement) (sand) (aggregates) (concrete)

4. Fiber Reinforced Concrete
Fiber reinforced concrete (FRC) is a composite material. It consists of concrete
plus fibers. These fibers enhance concrete's structural integrity. They improve
its resistance to cracking and impact.
Enhanced Durability

FRC exhibits improved
resistance to cracking.

Increased Strength

Fibers contribute to the
tensile strength of concrete.

Versatile Applications

FRC can be used in diverse construction projects

5. Condition :-

6. •Main role of fibers is to bridge the cracks that develop in concrete
and increase the ductility of concrete elements.
•There is considerable improvement in the post-cracking behavior of
concrete containing fibers due to both plastic shrinkage and drying
shrinkage.
•They also reduce the permeability of concrete and thus reduce
bleeding of water.
•Some types of fibers produce greater abrasion and shatter
resistance in concrete.
•Imparts more resistance to Impact load.
Why Fibres are used?

7. 1 Steel Fibers

High strength and toughness.

2
Synthetic Fibers

Lightweight and corrosion-resistant.

3
Glass Fibers

Includes polypropylene and nylon,
reduces shrinkage.

4 Plastic Fibers

Improves crack resistance and
reduces permeability.

Types of Fibers Used
(Steel Fibers) (Glass Fibers)
(Synthetic Fibers) (Plastic Fibers)

8. Plastic fibers
In plastic fiber reinforced concrete, plastic fibers are mixed with brick concrete
to enhance its properties, including crack resistance, flexibility, and durability.

9. Plastic fibers are a great choice. They increase impact resistance.
Plastic fibers also lower weight. Plastic offers chemical inertness as well.
This makes them ideal for specific applications

10. •Overuse of RCC where PCC is sufficient.
•Plastic fibers enhance PCC stability and durability.
•Enables PCC usage instead of unnecessary RCC.
•Reduces construction costs.
•Improves crack resistance and load-bearing capacity.

Environmental Benefits:
•Reduces plastic waste by repurposing recycled plastic fibers.
•Lowers carbon footprint compared to steel reinforcement.
•Increases sustainability in construction by reducing reliance on
non- renewable materials.
