This method will make the concrete stronger and is usually used for these types of structures. This method can also let structures hold for a longer time.

All was evacuated From this project, I learnt that we don’t really have to go to other countries to experience these landmarks, or landforms. Canada has got that! I found out that there are amazing features and interesting items within the CN Tower even though I never visited CN Tower before. When I got this project, I did not know anything about both towers, I have always thought that any tower in the world would be better than CN Tower. Even though I am still not sure about this statement after this one comparison, it still made me understand more about both landmarks and the good points about them. This project totally changed my view about this Canada’s symbol! In conclusion, I think that CN Tower is much better than Ostankino Tower in terms of the interesting features within. This was a surprising project and I had a lot of fun researching about both towers and their structure!
