5. Concrete
Concrete a mixture of cement water and aggregate has
been the foundation on which our cities and
infrastructures have been built for over 3,000 years.
Concrete is durable , flexible, and strong

6. Concrete is
the second most commonly used material on
our planet after water, but it also the second
biggest producer of CO2 emissions
in our planet

7. The problem is finite natural resources, The problem is
acidification of our oceans ,The problem is climate change
What's the problem?

8. Every ton of cement that we produce through the crushing heating and grinding of
limestone over three-quarters of a ton of carbon dioxide is released into our planet's
atmosphere

materials this concrete is more fire resistant more flexible and almost four
times stronger than conventional concrete
