Done by group: Alwakra_Gravity 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. The product idea is to solve two problems in one. The students' idea is to use the waste of car tires and recycled glass to improve the properties of concrete. Based on the research results the material used in the car tire is resistant to friction and strong with sufficient flexibility. On the other hand, the recycled glass is heat insulator, and resistant to 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. The material consists of concrete, cement, sand and
water with the addition of some kind of debris, such
as age or gravel. Concrete construction materials the
most important in the modern era, especially with the
iron to become the promotion of reinforced concrete.
Roman is the first to use ordinary concrete in history

4. Hunting for objects made of
concrete
Search and discussion about usage
of concrete in Qatar
-Concrete is used in everywhere

5. Learn how the reaction
happened in cement .

7. Day 1
1- The cement mixed with salt
is hardening fastest .
2- The cement mixed with
water is in between .
3- The cement mixed with
sugar is hardening slow.

8. Day 2
Comparing the density of different
mixture.
The highest density is 50:50, sand : gravels

9. Day 3

10. Day 4
-Test the strength of

-The hardest one is sample E

11. The product idea is to solve two problems in
one. Our idea is to use the waste of car tires and
recycled glass to improve the properties of
concrete. Based on the research results the
material used in the car tire is resistant to friction
and strong with sufficient flexibility. On the other
hand, the recycled glass is heat insulator, and
insulator to electricity.

12. In Conclusion :-
This product will use
the waste of car tires
and glass in improving
the properties of
concrete

13. The most thanks is to Ms. Fatima Nabhan for what
she taught us. Thanks for being an awesome
teacher and she was the greatest teacher for us.
She inspired us to do our best in achieving our
work.
Also we want to thank Ms. Amira for being with us
the whole time .Thank you for believing in us and
trusting us. Thanks for being there whenever we
needed you.
