Done by Steel Group, Ahmed bin Hanbal Independent Secondary school for boys Concrete is a composite material composed mainly of water, aggregate, and cement. We've chosen this product to participate in Qatar's 2030 vision and to help Qatar in the field of industry . the objectives are 1 - To make concrete durable 2 - To help the bases of buildings to stay for along life time . 3 – To reuse the industrial waste . 4- To improve concrete work-ability .

2. Activity 1 : Hunting for objects made of
concrete
 . Objective : searching for information
about concrete

3. Activity : Hunting for objects
made of concrete
1. Concrete is one of the most commonly
used materials in building .
2. There are many kinds of concrete such
as ((Reinforced concrete and Modern
concrete…etc))

4. Activity 2 : Comparing different kinds of
cements
Objective : Measuring the speed of hardening of
the cement when adding additives

5. Activity 2 : Comparing different kinds of
cements
Conclusion: adding calcium chloride )salt( to cement
helps to solidify Faster than adding sugar to the
cement as sugar slows the solidifying

6. Activity 3 part ( A ) : Comparing different
concrete formulations
Comparing different conceret formulations
Objective : Measuring the density of sand ,
gravil and the mix of them

Conclusion :The density of sand is higher than
gravil and the mix of them is the highest
density

Conclusion : The density of sample ( G ) is
higher than the density of sample ( E ) , on the
other hand sample ( E ) is stronger than
sample ( G ) .

14. Product
Ternary Blending Concrete

15. Product Idea
Ternary Blending Concrete
The main problems :
1- Concrete live short period of time .
2- Normal concrete is weak .
3- Shortage of fresh water in QATAR .
4- The effect of marine chlorides on concrete .
5- Reuse the industrial waste .
6- Sulfate attack .
7- ASR (Alkali – Silica Reaction)
8- Acid rains

16. Product Idea
Ternary blending
We've chosen this product to participate in Qatar's
2030 vision and to help Qatar in the field of
industry .
the objectives are
1 - To make concrete durable
2 - To help the bases of buildings to stay for along
life time .
3 – To reuse the industrial waste .
4- To improve concrete workability .

17. Hypothesis: Ternary blending
 Is the an possibility to use the sea water in the concrete ?
 Is the an possibility to use the industrial waste in the concerte ?
 Is there any concrete which lives long periods of time ?
 Is there any concrete which is considered as anti-sulfate ?
 Can we cure the effect of the marine chlorides on the bullied
concrete ?
 Is there any concrete which can hold high pressure ?

18. product story:
Ternary blending
We thought about the environment in QATAR and how to use it in
concrrete .
Due to the hot desert weather of QATAR and the lack of fresh
water we thought about using sea water in the concrete so we
searched about something that helps so we found about the
metakaoline .
QATAR environment is rich with sulfate and chlorides so we
searched about that problems and we found the flyash .
