Are There Alternatives to Concrete?
One of the world's pressing contemporary dilemmas centers on concrete, a well-established and widely used material that has recently come under scrutiny for its significant contribution to global greenhouse gas emissions. This arises from the energy-intensive nature of cement production
From scientific studies investigating the remarkable self-repairing capacity of Roman concrete, recycling initiatives, and innovations exploring the use of algae in concrete production, both the research community and the industry are committed to finding solutions that reduce the environmental impact of this material

1 年I think it is important to note that the concrete industry in North America has made significant strides in reducing its carbon footprint. We have been able to reduce our industry's continental overall carbon footprint by almost 22% over the last 7 years and we are continuing to reduce our GHG emissions. No other major material industry is able to make that claim. With that in mind, I believe it's also time to hold the other major industries accountable as well. The steel industry has the highest impact coming in at 11% (Global Energy Monitor, 2021) overall with the second being the wood industry at 10% (World Resource Institute, 2023) and then the global concrete industry is at 8% (Washington Post, CNN, 2023) so that begs the question: Why is the concrete industry singled out when compared to steel and wood? One answer: Deflection by the other industries. But to thicken the plot, MIT's Concrete Sustainability Hub has proven that exposed concrete has the ability to actually be an atmospheric carbon sink. So the material that has been vilified the most for it's carbon footprint is the one that is truly the most sustainable when compared to the other major material industries. It really makes you wonder, doesn't it?
