concrete.
Activity 2:
Comparing the
hardness of a
different kind of
cement by
adding salt and
sugar .
Activity 3:
Comparing
densities of mixed
aggregate at
samples
Activity 4:

Product
idea :
Intelligent
concrete

5. Cement

6. The concrete is
a very hard ​building material made
by ​mixing together ​
cement Fine aggregates Coarse aggregates water

7. Flexible
Durable
Cheap
strong

8. Hunting for objects made of concrete.

10. : Comparing the hardness of a different
kind of cement by adding salt and sugar .

11. sample A : cement
with water only
sample B :cement
with water and salt
sample C : cement with
water and sugar

13. sample temperature hardening Conclusion
A Slightly increased
then decreased
Quickly Reacted with cement
B Slightly decreased
then increased very
quickly
The fastest Salt act as a positive
catalyst
C Decreased then
Remained constant
Very slow Sugar act as a
negative catalyst

19. After We mix the ingredients we put it in
Paper Molds .

23. Some problems are facing vehicles drivers like darkness of the
road (when driving at night ) and unexpected weather
conditions . That’s why we aimed to solve these problems
through improving side walks by our product idea

24. Intelligent concrete

25. Material and Methods
To make an Intelligent concrete (lightening and heat
color indicator blocks ) we will use some organic
materials which have the capability to change thier
colors with changing in temperature and other
component that will radiate light
