Done by Rock group, Ahmed bin Hanbal Independent secondary school for boys Concrete is a composite  material composed mainly of water, aggregate , and cement We searched on the internet for a substance that prevent water to go inside the concrete and damage it or make some huge gaps.

2. Activity 1 : hunting for objects made of
concrete
Concrete is a composite material composed •
mainly of water , aggregate ,
and cement

3. Activity 2 comparing different kinds of
cement : slide 1
Calcium Table sugar
chloride salt
Portland Water
cement
Sample
D 400g 200ml 12g
E 400g 200ml 2g

4. Activity 2: Comparing different kinds
of cements
Mixing sample b and c

5. Activity 3 slide 1: Comparing different
kinds of cements
Conclusion : that sand is higher than gravel but , the mix
is the highest .
That salt with cement is the highest ratio of Harding cement , and
the water with cement is in the middle and the water with sugar
is the smallest .

6. Activity 3,slide 2 part (A) comparing
different kinds of cement
Activity 3 we measured the sand ,gravel and the mix of them .

7. Activity 3, part B: Comparing different
Concrete Formulations

8. Activity 4: Testing properties of
concrete
Objective : comparing different ratio of density .
Measure : measuring the mass of Gravel & Sand

9. Activity 4: Testing properties of
concrete

concrete
Our teem while testing the properties of concrete

11. Activity 5: reinforcing concrete
This is our group while we
were working on reinforcing
concrete

12. Design Project: Insulted Concrete
We searched on the internet for a substance that prevent water to
go inside the concrete and damage it or make some huge gaps .
•The substance name is Penetron this substance its used to prevent
water to damage the concrete .
• this is some explanation of what is Penetron : penetron is a
substance that prevent water or moisture to go inside the concrete
and make some troubles .
•If the moisture or the water is not in the area that concrete is
penetron will stay cool , is the water or moisture is found penetron
prevent those things , penetron is only used once for life time and is
also make concrete last longer .

13. Design Project: Insulated Concrete
Hypothesis
• 1: How will we find this material ?
We asked an engineer about this material he
said that its only used at Egypt and some
European countries .
• 2:Is it going to succeed ?
yes , its going to succeed if we used it right
• 3: How are we going to use it ?
• We will mix it with the concrete

14. Design Project: Insulted Concrete
Results
• Prevent water from negatively affecting the
concrete
• Increase concrete durability
• Increase concrete lifetime

15. Design Project: Insulted Concrete
Conclusion
Our project will affect in the new industry
of concrete, because we all know that water
or moisture affect the buildings negatively
and weakens its structured . It will almost
coast like 79$ for the kilo . And it will also
decrease the rate of repairing of the
building.
