• Introduction
• Activities summary
• Product Idea: Mind Water calcification
• Conclusion
• Acknowledgment

3. Introduction
 composites are materials made by combining
two or more natural or artificial elements (with
different physical or chemical properties)
 The component materials don’t completely
blend or lose their individual identities; they
combine and contribute their most useful traits
to improve the outcome or final product

4. Activities
Exploring the difference between
strength and stiffness
Testing different kind of ice
Designing a fishing pole
Testing a Foam Composites for
Strength and Stiffness

5. Project Idea
Mind Water calcification
 Introduction
 Anyone who uses a kettle to boil water, will have seen the effects of
lime-scaling. In fact, in some areas around the world you only have
to turn on your water tap and, unless you immediately clean the sink
after use, the lime-scale deposits start forming—sometimes even
visible to the eye!
 The reason for this is “water hardness”, which refers to the amount
of dissolved calcium and magnesium in the water. Hard water is
high in mineral content.
 Water hardness cause a lot of damage to water pipelines, storage
tanks and home appliances.
 Aim of the work
 Our aim to combine several materials together to reduce the
formation of lime-scale

6. Mind Water calcification
Methods and Materials
We search for materials that prevent the lime-scale
from depositing into surfaces and also lightweight to
make water pipelines and tanks. These materials are;
1- Teflon; can prevent minerals from bonding with
surfaces and makes it easier to remove deposits in
case they do manage to stick.
2- Carbon steel; the core of the tube that is strong
and corrosion resistant
3- Silica; lightweight material that can be formed and
dyed

7. Mind Water calcification
Results
Huge positive result and impact form this project are expected
when implemented’
1- Reduce drastically lime-scale formation
2- Reduce the damage to water pipelines and tanks
3- reduce the cost of maintenance of pipelines and tanks
4- Economic benefit nationwide to water supplying companies

8. Mind Water calcification
Recommendations
The project idea is proposed based on theoretical research
and studies, therefore its recommended to
1- Make and implement the project in real life for testing
2- Experiment with water from different resources

9. Conclusions
In conclusion, Al-Bairaq was a unique experience and a
unique way of learning through experiments
We learned a lot about composite materials and we were
able to come with a useful application that can help in many
aspects
