ARE NATURAL FIBER COMPOSITES ENVIRONMENTALLY SUPERIOR TO GLASS FIBER REINFORCED COMPOSITES?
INTRODUCTION:-
• Natural fibers have been used to reinforce materials for
over 3,000 years.
• Many types of natural fibers have been investigated for
use in plastics .including , Flax, hemp, jute, straw,
wood fiber, rice husks,wheat,barley,oats .
• Natural fibers have the advantage that they are
renewable resources and have marketing appeal.
• Natural fibers are increasingly used in automotive a ....etc

What is a Fiber…?
Small piece of reinforcing material
possessing certain characteristic
properties.
Can be circular or flat.
Parameter used to describe fiber –
“Aspect ratio”.
Aspect ratio is ratio of its length to its
diameter.
Typical aspect ratio for fibers ranges from
30 to 150.
Concrete (FRC)?
Fiber reinforced concrete (FRC) is concrete
containing fibrous material which increases its
structural integrity.
It contains short discrete fibers that are uniformly
dist ....etc

Abstract
This paper focuses on the experimental investigation carried out on high strength concrete reinforced with hybrid fibres (combination
of hooked steel and a non-metallic fibre) up to a volume fraction of 0.5%. The mechanical properties, namely, compressive strength, split
tensile strength, flexural strength and flexural toughness were studied for concrete prepared using different hybrid fibre combinations –
steel–polypropylene, steel–polyester and steel–glass. The flexural properties were studied using four point ben ....etc

Fiber Reinforced Concrete
“FRC is defined as a composite material consisting of concrete reinforced with discrete randomly but uniformly dispersed short length fibers.”
Fibers are generally discontinuous, randomly distributed through out the cement matrices.
Enhances flexural and tensile strength of the concrete.
Fibers may generally be classified into two: organic and inorganic.
Contd. ….
Volume fraction – measure of fiber in concrete.
Typically ranges from 0.1 to 3%.

GLASS FIBER REINFORCED CONCRETE

ABSTRACT:-
Glassfibre Reinforced Concrete or GRC is one of the most versatile building materials available to architects and engineers. Composed principally of cement, sand and special alkali resistant (AR) glassfibres, GRC is a thin, high strength concrete with many applications in construction.
The GRC-Glass Fibre Reinforced Concrete, which was first invented by 'pilkington' in UK and developed successfully by rest of the continent, is a product having unique combination of properties unch ....etc

Fiber Reinforced Concrete can be defined as a composite material consisting of mixtures of cement, mortar or concrete and discontinuous, discrete, uniformly dispersed suitable fibers. Continuous meshes, woven fabrics and long wires or rods are not considered to be discrete fibers.
Fiber is a small piece of reinforcing material possessing certain characteristics properties. They can be circular or flat. The fiber is often described by a convenient parameter called aspect ratio. The aspect ratio of the fiber is the ratio of its length to its di ....etc

I m Surya doing my final year in civil engineering. I have chosen to work on fiber reinforced Geo polymer concrete for my final year BE project. I would like to know the tests to be performed to assess the properties , instruments required and feasibility of the project. I'd be much obliged if someone could help me.
