Concrete is not glamorous. It is the workhorse of building materials: versatile, durable, and almost universally ubiquitous, with 30 billion tons of concrete produced every year. Cement, a component of concrete, produces 8% of the world’s carbon footprint.
Looking to lower that percentage, Purdue University engineers have discovered a way to make concrete more sustainable. Their new recipe for concrete has the potential to cut carbon emissions dramatically, creating building blocks for a better world.
