important and widely used material is called upon to possess very high strength and sufficient workability properties.
Concrete the most widely used construction material has several desirable properties like high compressive strength,
stiffness, durability under usual environmental factors. At the same time concrete is brittle and weak in tension. Efforts
are being made in the field of concrete technology to develop high performance concretes by using fibres and other admixtures
in concrete up to certain proportions. To improve the concrete properties, the system was named alkali resistance
glass fibre reinforced concrete in the present view the alkali resistance glass fibre has been used. In the present
experimental investigation the alkali resistance Glass Fibres has been used to study the effect on compressive strength
on M30 grades of concrete.
Fiber reinforced concrete (FRC) is concrete containing fibrous material which increases its structural integrity. This document discusses FRC, including its history, types of fibers used, applications, and mechanical properties. It also provides a case study comparing the effects of straight and hooked steel fibers on properties like workability, strength, and toughness. The study found that hooked fibers had better dispersion and increased flexural strength, toughness, and energy absorption compared to straight fibers. In conclusion, the document provides a detailed overview of FRC and how fiber type and content can influence its mechanical behavior.
Glass fibre reinforced concrete was studied by adding varying percentages of glass fibre to concrete mixes with grades of M25 and M40. Compressive strength tests were performed at 7 and 28 days. The maximum compressive strength was achieved with 0.20% glass fibre added to M40 grade concrete. In general, the addition of glass fibre increased the compressive strength of both grades of concrete compared to the plain concrete mixes without fibre. The study showed that glass fibre reinforcement can improve the mechanical properties of concrete.

Glass Fibre Concrete: Investigation on Strength and Fire Resistant PropertiesIOSR Journals
Abstract: Over the decades, there has been a significant increase in the use of fibres in concrete for improving
its properties such as tensile strength and ductility. The fibre concrete is also used in retrofitting existing
concrete structures. Among many different types of fibres available today, glass fibre is a recent introduction in
the field of concrete technology. Glass fibre has the advantages of having higher tensile strength and fire
resistant properties, thus reducing the loss of damage during fire accident of concrete structures. In this
investigation glass fibres of 450 mm length are added to the concrete by volume fraction of up to 1% to
determine its strength and fire resistant characteristics. Comparison of the strength and fire-resistance
performance of conventional concrete and glass fibre concrete was made. The paper presents the details of the
experimental investigations and the conclusions drawn there from
This document provides an overview of bendable concrete, also known as engineered cementitious composite (ECC). It discusses the development, composition, types, properties, applications, and conclusions regarding ECC. ECC is a mortar-based composite reinforced with short polymer fibers that provides much higher ductility than ordinary Portland cement, with a strain capacity of 3-7% compared to 0.01% for OPC. It uses a low volume of polyvinyl alcohol fibers and has proven to be 50 times more flexible and 40 times lighter than traditional concrete. Applications of ECC include repair of dams and use in seismic-resistant structures like bridges and skyscrapers due to its excellent energy absorption.

The document outlines a student's project for an Al-Bairaq program where they studied polymers, conducted experiments on polymer properties, and designed a humidity sensor using a polymer film. Their final project was designing a healing bandage using natural polymers like honey and cyperus, with the hypothesis that these would aid the healing process. The student concludes they gained presentation, research, and problem-solving skills from their experience in the Al-Bairaq program.
The document outlines a student project to design a degradable fishing net made from polylactic acid (PLA) polymer. The students conducted activities to learn about natural and synthetic polymers. They explored how polymer weight and concentration affects viscosity. Their fishing net design uses PLA, which degrades within 6-24 months when exposed to ocean environments, compared to hundreds of years for conventional plastics. The students conclude that converting fishing gear to biodegradable materials like PLA would help protect marine life and reduce plastic pollution.
The document summarizes several activities completed by students as part of an AL-Bairaq program exploring polymers. The activities examined properties of polymers like changing polymer pellets, identifying polymer products, and testing viscosity and strength of polymer films. The students also designed a humidity sensor using polymer film. Their final design project was an anti-microbial toothbrush using the polymer polyethylene glycol in the bristles to inhibit bacterial growth and reduce bacteria on toothbrushes. The students recommend further research into other anti-microbial polymers and improving their toothbrush design idea. Overall, the program helped students learn about various polymer applications and properties.
This document summarizes activities and a design project exploring polymers. It discusses:
- Activity exploring how polymer pellets change and hunting for polymer products.
- Activities comparing viscosity of liquids and testing strength of polymer films.
- A design project to create a humidity sensor using a polymer film that changes color with humidity.
- A project to generate electricity by inserting piezoelectric polymer films under keyboard keys. The project aims to reduce energy consumption and hypotheses that pressing the keys will generate voltage.
The document describes a student project exploring composite materials. It includes 4 activities where students tested different types of ice and foam composites to understand strength and stiffness. Based on their learnings, the students designed safety sports socks with layers of different composite materials like memory foam and bubble wrap to protect athletes' knees and ankles from injuries. The socks aim to help players in soccer and other sports prevent leg injuries. The students believe their low-cost composite sock design could benefit many athletes if adopted.
This document summarizes a student project exploring composite materials. The students tested different types of ice and foam composites to understand strength and stiffness. They then designed a fishing pole using composite materials. For their final project, the students proposed creating a dirt-resistant wallpaper using recycled polypropylene and rubber materials. They believe this wallpaper would be easy to clean and help beautify homes in Qatar while reusing waste materials. The students concluded they learned about composite properties and applications through hands-on activities and designing a new product.
The document describes a student project to create a glowing bracelet that uses light to help regulate blood pressure. The bracelet would contain ultraviolet and bright lights, which studies have shown can respectively decrease and increase blood pressure. If successful, the bracelet could help hypertension and hypotension patients manage their blood pressure. The students conducted experiments on light properties and developed a prototype bracelet using acrylic sheets and different light sources. Their conclusions were that light can be used for medical as well as decorative purposes.
Omar Bin Abdulaziz and his team explored biodegradable composite materials and proposed creating protective braces for cars using composites. They tested different materials and designed fishing poles to learn about composites. Their project idea is to make strong, lightweight and corrosion-resistant car braces from a composite of steel rods, carbon fiber, insulator spray and silica to protect vehicles during outdoor activities in Qatar's desert environment and prevent accidents and injuries. The braces are intended to reduce costs from car body damage and corrosion if manufactured and tested further.

Product Idea
3. • A composite material is made by combining two or
more materials – often ones that have very
different properties. The two materials work
together to give the composite unique properties
• Examples:
• reinforced concrete:
• mixture of cement-gravel-sand-water-steel.
• very strong- , durability and excellent thermal mass
(material for building).
• fiber glass:
• sio2 ,na2co3 and cac03
• good insulators, (make protective apparel for
astronauts and firefighters).
introduction
4. Activities 1: Testing Different kinds
of Ice.
•first we took three samples container and
marked each one with a letter(A-B-C)
At the end we put all the samples in the freezer for up
to 10 hours.
(sample A)
only water
(sample B)
blended tissue paper +water
(sample C)
blended tissue paper + water
+ other materials such
as(cork-cotton)
5. •After taking out the samples from the freezer we tried to
throw the samples from the same Hight to examine it
strength.
•Results: we can clearly see that sample c is the strongest
because it contained more than one material which
developed a very strong result.
samples Times of throwing Number of broken
picas
Sample A 1 5
Sample B 4 2
Sample C 6 none

6. Activities 2: Hunting for
Composite Materials.
• Composite materials are widely
used in the Aircraft Industry and
have allowed engineers to
overcome obstacles that
includes using the materials
individually.
• The constituent materials retain
their identities in the composites
and do not otherwise merge
completely into each other.
Together, the materials create a
'hybrid' material that has
improved structural properties.
Common composite materials
used on airplanes include
fiberglass, carbon fiber, and
fiber-reinforced matrix systems
or any combination of any of
these.
7. Activities 2: Hunting for
Composite Materials.
Weight reduction is the single greatest
advantage of composite material usage and
is the key factor in using it in aircraft
structure. Fiber-reinforced matrix systems
are stronger than traditional aluminum
found on most aircraft, and they provide a
smooth surface and increase fuel efficiency,
which is a huge benefit.
Also, composite materials don't corrode as
easily as other types of structures. They
don't crack from metal fatigue and they
hold up well in structural flexing
environments. Composite designs also last
longer than aluminum, which means fewer
maintenance and repair costs.
8. Activities 3: Exploring the Difference
Between Strength and Stiffness.
Strength: The property of materials by which
they endure the application of force without
yielding or breaking.
Stiffness: rigid or firm; difficult or impossible to
bend or flex.
First We took different materials such as:
(Steel rod -Nylon rod-Pasta-Wood rod-Plastic
rod)
And we test the strength and stiffness for every
material.
9. Activities 3: Exploring the Difference
Between Strength and Stiffness.

2 Nylon rod Plastic rod
3 Plastic rod pasta
4 Wood rod Wood rod
5 pasta Steel rod
Results:
10. Activities 4: Testing a Foam Composite
for Strength and Stiffness.
• This experiment was about testing the
strength and stiffness of 3 samples of
cork
• Sample(A)cork only
• Sample(B)cork with tape on top
• Sample(C)cork with tape on top and
bottom
• And then we affected on them with
different weight each time
• .meanwhile using a ruler to help us
locate the distance of the cork after
the weight was applied.
11. Activities 4: Testing a
Foam Composite for
Strength and
Stiffness.
•sample (A) was the weakest
because it broke so quickly unlike
sample(B) which just got bent .
•Results:
•sample(C) is the only sample that
didn’t loose it shape because of
how putting the tape on top and
bottom created a support that
build a strength and stiffness to
the material.
12. Design Project: Designing a
Fishing Pole
Materials:
2 straws
Gauze
Tape
Bendable metal wire
Steps:
-First, we stick 2 straws using the tape.
-then, we added the bendable meatal
wires
by rolling it around the straws.
-After that, we placed the gauze around it.
Finally, we taped it once again to make it
more stronger.
13. Design Project: Designing a
Fishing Pole
• While we were designing the
fishing pole we made sure that it is
going to be:
• -Light Weight
• -Strong
• - Flexible
• And by adding different kind of
materials we tried to produce the
best product in order to achieve all
our goals.
14. Why did we
choose this
project?
•Through time we have found out that
the car steering wheel start to become
old and easy to crack, in addition to
that ,the weather is often hot in Qatar
so the sunlight can easily breakthrough
and damage the steering wheel which
can make it unusable. Nowadays you
see that people have already started on
making steering wheel covers that can
protect it but after putting those covers
into the test we can still clearly notice
that it is not doing it’s job as it should.
Unti-crack heat resistant steering wheels
15. What is our project idea?
•After testing how covers failed to do there
job we find the best is to invent a cover that
includes many materials each one has its
own properties. What is special about it is
that it is not like any other cover because
our materials have specific properties to
protect the wheel for a much longer time
than the typical covers, we even came to
realize that drivers can get annoyed,
discomfort or even experience to get
burned by touching the hot wheel therefor
our project can actually make the cover
cooler by adding materials that can insulate
and reflect any heat.

16. What are the materials?
Unti-crack heat resistant steering wheels.
materials What dose it do? photo
Plastic rubber It is a primary object of the present invention to
provide a resilient or flexible steering wheel
which has rigid skeleton or framework covered
with flexible material.
Glass fiber It is stronger than many metals by weight
and can be molded into complex shapes
Styrofoam Dose a good job of keeping things cold
because the material is a poor conductor
of heat and it has millions of tiny air
bubbles that slow the progress of heat
through the material
Minor wool fabric It is a soft thick fabric that can make the
perfect layer at the end of the cover.
Cooling gel pad acts s a thermally insulating pad
17. We had chosen
different materials
each one has it’s
special property, we
are going to add many
layers each one with
different material to
support the steering
