By Energy Rant No Comments
Over the years, I’ve seen numerous mentions of decarbonizing concrete or cement. Random articles describing the need and means to decarbonize cement include this McKinsey article, this DOE post, and this Canary Media article. Those don’t cut it for me. I set out to explore cement making and why it is so carbon-intensive. But first, some terminology review is advised to differentiate cement from concrete.
