Group Name: TBZ_Rocksoild7 School Name: Tariq Bin Ziyad Independent Secondary School for Boys This module enables the students to study concrete properties in general through experiments done by the students. Some types of concrete can absorb the heat therefore we can use the concrete in heating. After studying such types of heat conductive concrete the idea of making water heater by concrete clicked our mind.

4. What is Concrete ?
Concrete is An artificial stone-like material
used for structural purposes. It is made by
mixing cement and various aggregates, as
sand, pebbles, gravel, etc., with water to
harden by hydration.

by concrete

29. Product story
The weather in Qatar and other Arabian
countries is mostly hot . But we can use this high
temperature in making something odd
for instance we may use it in heating something
and this idea was very attractive to our team as
we got a new idea of making water heater by
working this high temperature which may
produce electricity in future. It wasn’t that easy to
find and gather the data but what special we got
is Motivation which kept up warm all the time .
