Cement

Cement is a compound that connects Bricks and is toxic.
==Question==
===Why does the Burj Khalifa not use cement?===
If you look closely, then you will see it is glass. See? Nothing to do with the cement. But I’m afraid this is actually a cheap trick if YOU built it, it has many expensive glass windows.
=== Back to the Brain ===
The compound is AI2O3. Mostly, but now just chill out. Can’t you add Ozone to this compound?
