Concrete is the most used human-made product on the planet. From the buildings, bridges, and roads you see around you right through to the curbs beneath your feet, it's an essential construction material you'll meet up with daily.
A key ingredient in concrete has always been cement, the production of which accounts for around 8 percent of the world's greenhouse gas (GHG) emissions. While it may be tempting to think we are living in the age of plastic—after all, we have generated around 8 billion tonnes of plastic over the past 60 years and it turns out that the cement sector produces more than 30 billion tonnes of concrete each year.
