The Colosseum in Rome, the Olympic Stadium in Montreal and the Burj Khalifa tower, the tallest in the world, were all built using concrete. Our scientific duo, consisting of Chantal Srivastava and Joël Leblanc, were interested this week in this material selected for the construction of the buildings. However, the two journalists emphasize its main disadvantages for the environment, although solutions to make it greener are being made in Canada.
Chantal Srivastava describes why concrete is the most widely used building material. Joël Leblanc points out the differences between cement and concrete.

The duo lives on the enormous impact of making concrete on greenhouse gas emissions. Chantal Srivastava also explained that concrete causes problems because of its main ingredient: sand.
Finally, the journalist cited the example of several Canadian companies that are diversifying to make concrete less energy efficient.
