2. • Introduction
• Activity 1: Hunting for objects made of
concrete
• Activity 2: Comparing Different Types of
Cement
• Activity 3: Comparing Different Concrete
Formulation
• Activity 4: Testing Properties of Concrete
• Design Project : Concrete Reinforcement

3. Concrete is mixture of cement, coarse
and fine aggregates and water, it is
used in building houses and bridges.
What is concrete ?

4.  Objective: to recognize different uses of concrete.
 We searched in the internet about the concrete( what
its use, where it is used, what is its formation)

5. • Results: we found out that the concrete is a
mixture of cement , coarse and fine
aggregates and water, and it is used in
building.

6.  Objective: Observe the chemical and physical change,
as cement hardens
 We made three types of concrete ( cement with water)
and (cement with water with salt) and (cement with
water with sugar) .

7. • Results : we recognized that adding salt
with the concrete makes it hardens fast.
However, adding sugar makes it hardens
slowly.
• Conclusion: Salt is a catalyst factor for
hydration, whereas, sugar is a inhibitory
factor.

8.  Objective: Compare the densities of different concrete
formulations
• We measured specific
masses of some substances
and mixed them together,
then we measured the
volume of the mixture and
got the density.

9. • Results: Putting same percentage of fine
and coarse aggregates make the density
increases, consequently, the strength
increases.
• Conclusion: we recognized that the density
depends on the percentages of the
substances in the mixture

10.  Objective: Making different concrete formulations
Activity 3: Comparing Different
Concrete Formulation (Part B)
• We made different types
of concrete with different
percentages of cement,
fine and coarse
aggregates, and water.
After that we put them in
templates witch we made
from paper.

11. • Results : we have seen that the concretes
are different in hardness, some of them are
weak and some of them are strong
depending on the material used to make
mixtures.
• Conclusion: water in concrete mixture
evaporates leaving voids increasing voids
will make concrete less dense
Activity 3: Comparing Different
Concrete Formulation (Part B)

12.  Objective: To test the properties of concrete including
strength and brittleness and observe how its
components affect those properties
• Procedure: we used
testing apparatus to
test for concrete
strength

13. • Results : two mixture of concrete we made
were B and E. E was stronger because it has
equal amounts of coarse and fine
aggregates.
• Conclusion: using equal amounts of coarse
and fine aggregates will make concrete
mixture stronger.

14.  Objective: Concrete reinforcement by adding
different materials to the mixtures.
 We choose metal to reinforce concrete mixture

15.  Results: (E+) concrete mixture was strong it
withstand 10kg of weight pressure during pouring
water in the bucket.
 Conclusion: Reinforcing concrete (E+), it became
stronger able to bare big pressure

16.  We all heard about the rust which happens to the metal which
reinforcing the concrete, and this became a big problem.
Consequently, we chose this project.
 We heard also about many solutions for this problem, but most
of them are not effective. That which made us think about a
creative and functional way to solve this problem.
 In this project we use some materials that makes the concrete
waterproof and stronger.
 We think that our project is special because we used some
materials which nobody used together.

17.  We suppose that adding silica, calcium chloride and bitumen to the
concrete makes it waterproof and stronger.

18. we used to perform this project silica, calcium
chloride and bitumen

19.  After we tested our product we found that it is stronger and waterproof.
 We can use this project in bridges and oil fields. Therefore, we will save
the concrete from water which case rust to the metal which reinforcing
the concrete.

20.  We recommend that our project be used every where(
in bridges, oil fields, building ) because of its
importance.
 We recommend that our project be developed to be
used for another applications.

21. Doubtless, we have gained a lot of benefits through our
participation in Abiraq such as; we learnt how to work
with a team seriously, we learnt new things about
concrete, we learnt how to innovate new ideas.
Finally, it was a great experience and we hope to have it
again.

22. Many thanks to my teachers, school and AL-Bairaq team
from Center for Advanced Materials (CAM), Qatar University
for supporting us during our journey with a AL-Bairaq.
Also, I would like to thank the sponsors UNESCO, Qatar
National Commission,and Shell.
