Concrete is the second most consumed material on Earth after water. It is a great material with which you can build any structure above, below, or even underwater, whether it is a floor or two or a skyscraper. In this episode, we will learn about the history of concrete as a material, what were the ways in which humans built before the advent of concrete, and how did we reach these huge consumption rates? We will also learn about its advantages, its disadvantages and the problems it caused to the environment, and what solutions engineers and scientists are proposing to solve its problems. #Aldaheeh Sources San Francisco Earthquake Sources -https://earthquake.usgs.gov/earthquak... -https://www.loc.gov/item/00694425 https://www.erih.net/how-it-started/s...
