Done by Group : Talent School Name : Al Resala Independent Secondary School for Girls. Composites Module : through this module , students learned that the composite material can be defined as a mixture or combination of two or more material , they did many activities to test some properties for composite materials like stiffness and strength. the product Idea is : The Optimum Concrete is concrete with special prosperities like saving the cost , keeping the building cold in summer and hot in winter and absorbing humidity.

3. INTRODUCTION
Composite:
A combination between two or
more visible distinct materials to
form new materials with
improved
properties.

4. ACTIVITY(1): TESTING DIFFERENTKINDSOF ICE.
STEPS OF TESTING DIFFERENT KINDS OF ICE :
2- Then we labelled it( A,B,C) .
3- In Petri dish A: we put pure water.
4- Petri dish B: water + tissue
5- petri dish C: water + tissue + cotton +
straw6-Finally, we put it in the fridge
1- We took 3 Petri dish .

5. ACTIVITY (1): TESTING DIFFERENT KINDS OF
ICE.
Petri dish (C) was
the strongest one
while petri dish (A)
was the weakest
one
Adding many
materials makes the
ice stronger

6. Types of composites
composites
Particulate
composite
Laminar composite
Fiber-reinforced
composite
Activity(2):Hunting for composite
materials Natural
wood
Synthetic
concrete

7. ACTIVITY(3):EXPLORINGTHE DIFFERENCE BETWEEN
STRENGTH AND STIFFNESS
Strength
Stiffness : is a measure of how much a
material will deform by bending
We took some material to discuss
about it , And we tested the materials
for strength and flexibility

8. ACTIVITY(3): EXPLORING THE DIFFERENCE BETWEEN
STRENGTH ANDSTIFFNESS
1 steel rod 2 Nylon Cord
3 plastic rod 4 wood rod
5 pasta
Strong -------weak

9. ACTIVITY(3): EXPLORING THE DIFFERENCE BETWEEN
STRENGTH ANDSTIFFNESS
Most flexible --------Least flexible
1 Nylon Cord 2 plastic rod
3 steel rod 4 wood rod
5 pasta

10. ACTIVITY(4):TESTING A FOAM MATERIAL FOR
STRENGTH AND STIFFNESS
In this activity we took 3 sample:
-Sample A : plain foam
beam
-sample B : one side paper
-sample C : two sides paperThan we compare between
3 samples and took
measurements

11. ACTIVITY(4):TESTING MATERIAL FOR STRENGTH AND
STIFFNESS
g Plain foam (A) One side
paper (B)
Two side
paper (C)
0 9 9 9
200 9.5 9.5 9
400 10 9.5 9.5
600 10.6 9.5 9.5
800 11 9.75 10
1000 12.5 10 10
Mass (g) Length (cm)

12. CONCLUSION
Foam with two sided paper
was the strongest one while
Plain foam was the weakest
one

13. DESIGNINGA FISHING POLE
The fishing pole must be :
1 strong
2 flexible
3 light

14. FINAL PROJECT:
THE OPTIMUM CONCRETE
From Qatar vision 2030 Qatar is a young country so its interest in
construction so we try to make some concrete with special
prosperities like
Save cost, keep the building cold in summer and hot in winter,
absorb humidity
-we think our project useful for country , we learn from this cycle
some information about composite materials that help us to make
our project
.
The Aim of our project to find concrete with special prosperities
(cheaper-insulator -control local humidity……)

15. HYPOTHESIS: (‫)الفرضية‬
We expect that the materials will make the concrete:
1- stronger ,
2- stiff,
3- cheaper ,
4-decrease the humidity

16. AMAZING CONCRETE
METHODS AND MATERIALS
Materials :
we added materials to the concrete
( iron ,clay, silica gel , rough clothes )
Methods
Sample 1 : concrete with silica to decrease humidity
Sample 2 : concrete with iron to give it strength and help in recycling
Sample 3: concrete with clay to make it cold in summer and warm in winter
Sample 4: concrete with rough clothes to give strength
Sample 5: the Optimum concrete which has all the materials
With new prosperities
.

17. RESULTS
The Optimum concrete
Will solve a big problem because it has anew properties
and amazing concrete

18. RECOMMENDATIONS
1-We recommend the government and company to take our project and
try to use in the construction.
2-we advise the company to make a testing for the project related to
(stiffness , humidity , hardness and strength )
3- we advice to make more investigation for improvement of the
optimum concrete

19. CONCLUSIONS
when we added new materials to the concrete
These materials improve the prosperities for
concrete
.
