3. INTRODUCTION
Concrete was first discovered by Joseph Aspdin
in 1824.it is a mixture of water ,cement ,sands
and coarse aggregate. Concrete is used in
buildings , bridges , roads,..etc

4. ACTIVITIES 1: HUNTING
FOR OBJECTS MADE OF
CONCRETE
– Objective: to recognize different uses of concrete.
– We searched in
the internet
browser for what
is concrete made
of and what is it
used for ?.

5. ACTIVITIES 1: HUNTING
FOR OBJECTS MADE OF
CONCRETE
– Results : we discovered that
concrete is made of mixture of
water ,cement ,sands and coarse
aggregate, and used in
buildings, bridges, and roads.
– Conclusion: we discovered
concrete is used everywhere
because it is strong, formable
and cheap.

6. ACTIVITIES 2: COMPARING
DIFFERENT TYPES OF
CEMENT
–Objective: Observe the chemical and
physical change, as cement hardens
In this experiment we tried three
different cups with the same
amount of cement but each cup had
a different solution. Cup (A) we
added only water. Cup (B) we added
water and salt. Cup (C) we added
water and sugar.

7. ACTIVITY 2: COMPARING
DIFFERENT TYPES OF
CEMENT
– Results:we found out that cup (B)
with salt and water was the fastest
to be solidified, followed by cup
(A). The last cup (C) was the last to
become solid.
– Conclusion:
– we discovers salt
motivate
– concrete elements to get
solidified faster and
sugar make concrete
solidified too much slow
.

8. – Objective: Compare the densities of different
concrete formulations
– We measured the density
of different formulas of
sand and aggregate by
dividing mass over volume
and test if there is a
difference in the
density, if the quality
concrete different.
Activity 3: Comparing
Different Concrete
Formulation (Part A)

9. – Results: we found out that
concrete needs equal amounts of
course and fine aggregates to be
strong, and have high density.
– Conclusion: Mixing coarse and
fine aggregates in equal
portions will fill more spaces
and will results in higher
density concrete
Activity 3: Comparing
Different Concrete
Formulation (Part A)

10. – Objective: To test the properties of concrete including
strength and brittleness and observe how its components
affect those properties
– We started by building paper molds
to hold our concrete mixture.
– We mixed three samples of concrete
as shown in the following table:
Sample Fine
aggregate
s (g)
Coarse
aggregate
s (g)
Cement
(g)
Water (ml)
G 120 120 60 45
E 120 120 60 33
Activity 3: Comparing
Different Concrete
Formulation (Part B)

11. – Results: water to cement
ratio affect density of the
concrete
– Conclusion: Density of
concrete decreases as
water to cement ratio
increases
Activity 3: Comparing
Different Concrete
Formulation (Part B)

12. Activity 4: Testing
Properties of Concrete
– Objective: To test the
properties of concrete
including strength and
brittleness– Using strength
test apparatus to
test strength and
brittleness of
samples made in
previous activity

13. Activity 4: Testing
Properties of Concrete
–Results: We found out that the strongest
was (E) and the weakest was (G).
– Conclusion: Concrete formulations having
equals amount of fine and coarse aggregates
and less amounts of cement to water ratio
will have higher strength.

14. DESIGN PROJECT CONCRETE
REINFORCEMENT
–Objective: Concrete reinforcement by
adding different materials to the
mixtures.
– We add metal
under concrete ,
in medal and up.

15. DESIGN PROJECT CONCRETE
REINFORCEMENT
– Results : We discovered that
concrete is able to handle
compression more than tension.
– Conclusion: adding
reinforcement will make
concrete stronger, and make
concrete able to handle
tension.

16. FINAL PROJECT:
(GLOWING CONCRETE )
This project is important for
the drivers. We can use glowing
concrete in street paving to
reduce the number of traffic
accidents , we can use it to
decoration the building and save
the energy .

17. GLOWING CONCRETE
METHODS AND MATERIALS
We thought that if we add
photoluminescence to concrete it will
glowing but as an alternative we add paint
glow in the dark .
we make concrete from both fine and coarse
aggregates and water, in one mixture we
mix paint with mixture in the other sample
we painted concrete block after it dries.

18. GLOWING CONCRETE
RESULTS
– Painting concrete with
glow in the dark paint made
it glow

19. GLOWING CONCRETE
RECOMMENDATIONS
Making concrete glow by using glow in
the dark colors to make it glow in a
cheap way which can help us reduce usage
of electricity
do more experiences and search about
other materials to our project to get
glowing concrete.
There are many uses to glowing concrete
in street paving, decoration to
building,…etc .

20. CONCLUSIONS
We have learn much thing from Al-
Bairaq about concrete, this program
learn as to believe ourselves and
make us love discover things.
Thanks for all that

21. ACKNOWLEDGMENT
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.
