TED: A concrete idea to reduce carbon emissions | Karen Scrivener

Concrete is the second most used substance on Earth, contributing to 8% of man-made CO2 emissions. While essential for infrastructure, its production, particularly cement, is a major source of emissions. Innovations like LC3, which combines limestone, calcined clay, and cement, offer a solution with up to 40% lower emissions. LC3 can be produced using existing equipment and is being adopted globally, promising significant CO2 reductions and aiding in climate change mitigation.

What are the potential benefits of using calcined clays in concrete production?

Why is it challenging to replace Portland cement with alternative materials like LC3?
