Done by group: Alwakra_Gold School Name: Al Wakrah School for girls Concrete module: This module enables the students to study concrete properties in general through experiments done by the students.Finally they use what they learn to design their own product. Through their research, students found that one of the very important problems that need to be solved in Qatar is the rise of using electricity. Here they suggested the idea of their project, which is using alternative energy to generate electricity instead of burning fuel. This can be achieved by building flexible bumps that can convert the pressure generated by the vehicles into electricity.

2. • Introduction
• Activity 1: Hunting for objects made of
concrete.
• Activity 2: Comparing different kinds of
cement
• Activity 3: Comparing different concrete
formulation .
• Design Project: testing the strength of the
concrete
• Product Idea
• Conclusion
• Acknowledgment

3. • Concrete is used as a basic infrastructure material in
buildings and it's made up of mixture of cement,
water , fine aggregate and coarse aggregate

4. Objective:
Discussion about usage of concrete in Qatar
Conclusion :
Concrete is used everywhere
around us.

5. Uses of concrete:
Street
Building
Bridge

6. • Objectives:
• 1-learn how the reactions happened in cement.
• 2-how cement change its properties.
Procedure Results

8. Part A : Comparing the densities of different
formulations.
Results : Measuring the density of different mixture of sand and
gravels . 50:50 sand to gravels ratio gives the highest density

9. Part B : Making the concrete samples.

12. Objective :Breaking concrete
Results : We can illustrate the results of the experiment through
this table :
ResultsSamples
•The strongest one
•Broken hardly after 5000
ml water
E with reinforcement
•Medium strength
•Broke after 2500 ml of
water
E without reinforcement
•The weakest
•Broke at the first moment

13. Breaking concrete: Reinforcing concrete gives a much
stronger structure

14. • Objective : Connecting electricity using solar
energy
• Procedure/prototypes: Concrete , solar panel,
flexible additive such as silica , using sensor (
strain gauge ) .
• Results: reduce the usage of non-renewable
energy

15. • Introduction and Rationale:
• After development in Qatar , the usage of
electricity is increasing due to the increase in
population. Here comes the importance of our
product in Qatar.
• Aim of the work :
• use alternative energy to produce the electricity .

16. The circuit of the bump

17. •Hypothesis:
•This products will decrease the usage of electricity.
• Use alternative energy as a new way to generate
electricity .

18. Our product story:
From our experience with Al Bairaq team , we found that one
of the important problems that need to be solved in Qatar is
the increasing use of electricity. Accordingly, we thought of
using alternative energy instead of electricity.

19. Results:
This product is environmentally friendly .

20. Our product is very useful, and we hope we can
help our country by applying our products
idea.

21. We would like to show our thanks and
appreciation to Ms. Amira who helped us
during Albairaq, the school’s
administrators who supported us and
Albairaq’s team who give us this
opportunity
