Done By :Professors Group School Name :Al-Karana Independent Secondary school for Girls Concrete : In this Module students learn the properties of Concrete and its features and contents and also knowing the different between cement and Concrete and the importance on adding reinforcement materials on Concrete samples. Adding Plastic Waste to Concrete: in order to increase concrete strength, we add the plastic waste into the concrete Sample We also will use the unwanted Plastic waste as recycling

2. Outline
• Introduction : to concrete Module
• Activity 1: Hunting for objects Made of concrete .
• Activity 2: Comparing different kinds of cements .
• Activity 3: Comparing different concrete formulations
• Activity 4: Reinforcing concrete
• Activity 5: Testing Properties of concrete
• Product Idea : Adding Plastic waste to concrete

3. Introduction
Concrete : is a mixture of cement , water , and
aggregates that , when poured into a mold
eventually hardens and takes the shape of
the mold ..

4. Activities (1) Hunting for objects Made of
concrete
- Hunting for objects Made of concrete .
(Buildings , Bridge , Street )

5. Activity (2) comparing different kinds of
cements .
• Objective :
Knowing the effect off adding Cacl2 and Sugar to
concrete sample.
• Procedures :

6. Results:
Samples Harding rate Temperature
Water, CaCl2 and
cement
Water, sugar and
cement
Conclusion:
Adding CaCl2 increase hardening rate and
adding sugar will decrease hardening rate.

7. Activity(3): comparing different concrete
formulations
• Objective: Discover how density will change with different portions of
aggregates.
• Procedure:
Sample 100g fine aggregate 100 g coarse
• Results:
A B C
aggregate
Mix (50g fin
aggregate and
coarse aggregate)
volume 1 less volume 2 3 high volume
C A B
• Conclusion: C sample give us less volume which will be good for density.

8. Activity(3): comparing different
concrete formulations
Results:
Samples is ready to test

9. Activity(4): Reinforcing concrete
We add a reinforcement
material to concrete sample
name E+ and all samples now
is ready to test

10. Activity(5): Testing Properties of concrete
We took the concrete that we did in our last
activity and checked which formulation was
strong.

11. Activity(5): Testing Properties of concrete
Sample Contains Applied weight need

E Cement + Water + coarse and fine
aggregate 50%

E+ Cement + Water + coarse and fine
aggregate 50% + reinforcement
materials
9kg
C Cement + Water + coarse

4.5 Kg
Conclusion :
we found the 50% of sand , 50% of gravels , 50% water to cement,
sample is the strongest of all the samples and the best one for
concrete.

16. Acknowledgment
Thank to all people, teachers, friends, and our school that
supported us during our journey in AL-Bairaq project.
Also we would like to thank AL-Bairaq team and the sponsors
who gave us the opportunity to participate in AL-Bairaq project,
create and innovate.
