Project done by platinum group of Aisha Bint Abi Bakr for Girls . Students study concrete properties in general through experiments. They will study the hardening process of concrete and they will prepare different formulations of concrete samples. Then, they will study different concrete properties and examine the strength of their samples to get the best concrete formulation. Finally, they use the knowledge gained during the workshop to design new concrete products. The product Idea is light concrete where the idea is to form a concrete paving system depend on LED instead of the light bulb that is distributed on the street as it will save the amount of electricity used and reduce the no. of accidents.

2. Outline
• Introduction
• Activity 1: Hunting for an object made of concrete
• Activity 2: Comparing different kinds of cement
• Activity 3: Comparing different concrete
Formulation.
• Activity 4: Reinforcing concrete
• Activity 5: Testing properties of concrete
• Product Idea: Light concrete

3. Concrete
• Concrete is a substance consisting of
cement, sand and water and other
additives and reinforcements included to
achieve the desired physical properties.

4. Activity 1: Hunting for objects made
of concrete
Bridge
Streets
Buildings

5. Activity 2: Comparing different kinds
of cement
• Objective: knowing the effect of adding Cacl2
and sugar on concrete sample
Procedure: A mixture of water and cement /
water mixture and cement and salt / water
and cement and sugar mixture

Result : The Harding rate decrease when we add sugar
and increase when we add Cacl2
Conclusion : Cacl2 is positive catalyst

Results :
The mixture C show a low volume
which mean high density

16. Final Project:
Light concrete
The idea is to form a concrete paving system depend on LED instead of
the light bulb that distributed on the street as it will save the amount of
electricity used and reduce the no. of accidents.

19. Light concrete
Results:
The results is a concrete paving blocks which we'll be
established in street instead of traditional light bulbs
which consume a lot of power and electricity.

20. Light concrete
Recommendations:
-It's recommended to use nor only as paving but also in many
areas :
Outlining of driveways and parking areas,
Staircases,
Swimming pools,
Paths,
Illuminate gardens,
Illuminate facades of buildings
-It's recommended to do further researches to our project to be
used without batteries or electricity and charges by normal
sunlight or UV Light

21. Conclusions
We have used less electricity and
we add the beauty of the streets

22. Conclusions
In conclusion, concretes are vey important
thing in buildings around the world. People
must know how to make strong concretes , we
learnt that from AL-Bairaq workshop and gain
an experience on how to form and test
concrete samples.
