Cement Displacement & Decarbonization Decade By Decade Through 2100

Cement is the gray glue that holds our economy together. It’s ubiquitous, if often hidden behind paint or plaster. It holds together the rock, sand, and steel that keep our buildings upright, our bridges spanning chasms, and our dams holding water for irrigation, generation, and recreation. And it’s a carbon … [continued]

Decarbonizing Cement & Concrete Is Noble, But Why Will Developers Pay For It?

During what has become concrete month, I’ve explored the full range of actual and purported solutions to the climate problem that is the cement, steel, and concrete used in construction. The industry’s emissions are high, with every ton of reinforced concrete having a carbon debt of 0.3-0.4 tons of carbon … [continued]

Steel Reinforcement Is The Invisible Miracle Of Concrete Construction, But Comes With A Carbon Price

Reinforced concrete was invented in the mid-19th century, a game-changer in the construction world. French gardener Joseph Monier is often credited with its creation. While experimenting with materials to build stronger garden pots and tubs, he had the idea to combine concrete with iron mesh in 1849. Monier patented his … [continued]

How Much Does Sand, Grit, & Gravel Add To Concrete Carbon Emissions?

During concrete day… errr … week … errr … verging on two weeks this time, I’ve explored a lot of carbon emissions solutions for the full value chain of the gray glue that ensures our buildings don’t collapse, our bridges stay up, and our underground working chambers don’t pancake. We … [continued]
