Done by Cement team in Qatar Independent Technical School for Boys. Concrete is a composite material composed of water, coarse granular material (the fine and coarse aggregate or filler) embedded in a hard matrix of material (the cement or binder) that fills the space among the aggregate particles and glues them together. This module enables the students to study concrete properties in general through experiments done by the students. Nowadays, airplanes are taking a huge contribution in our life. We all depend on air flight to travel from place to place. The most important thing we look for in our air flights is safety. This project considers adding more safety to air flights and airports. When a plan lands, the force of friction generates heat that can lead to a spark or destroy Tires that consequently can lead to a fire or a disaster. So we added some aggregates to concrete that will absorb heat and thus guarantees us safer flight.

3. Examples of concrete
Activity1: Hunting for objects made of concrete

5. cement:
is a binder, a
substance that sets
and hardens as the
cement dries and also
reacts with carbon
dioxide in the air
dependently


How much concrete used in burj
khalifa?
Over 45,000 m3 (58,900 cu yd) of
concrete, weighing more than
110,000 tonnes were used to
construct the concrete and steel
foundation,.

7. Activity1
Since ancient times
rock has been an
important
infrastructure material
For example ancient
egyptians used
limestone blocks to
build the pyramids

8. Activity2: Comparing Different Kinds of Cement
We made three cement mixtures, one
with sugar, one with salt and the last
one was plane cement.
The reason behind this experiment
was because we wanted to test how
these elements are going to effect the
concrete mixer, and we found out
that sugar slows the concrete
hardening process while salt actually
makes this process faster.

11. ACTIVITY3: COMPARING DIFFERENT CONCRETE FORMULATIONS
• We had to choose from different materials and we were introduced to different
materials and when we told to choose from materials
• We chose Steel,Nails and wooden sticks

12. ACTIVITY-4: TESTING PROPERTIES OF CONCRETE
(STRENGTH)
The instructors told us to break
our cement using the figure
show below we had to put the
concrete between the bottom
support and we had to put
some water in the bucket till
the top loading cylinder drops

14. We put a lot of materials and
thanks to that we won first
place and it took a long time
to break it took 30 kg to
break and that shows that
more materials you put in
cement will strengthen it
even more
Activity-4: Testing Properties of
Concrete – (Brittleness)

16. New Runaway for airports
Planes will have less accidents if we use
cement as the main runaway for
airports because when we use it, it will
cool down the wheels and when we do
that it will make for better runaway and
it will not heat up the wheels as we saw
in the past.

17. Acknowledgment
Many thanks to my teachers, school and Albairaq team from
Center for Advanced Materials (CAM), Qatar University for
supporting us during our journey with a Albairaq.
Also, I would like to thank the sponsors UNESCO, Ras Gas,
Shell and Qatar Petroleum.
