The best description of life on a building site I know of is provided in the first six minutes of this video featuring the late great Sean Lock. https://www.youtube.com/watch?v=s_6-tGTaG_g&t=353s
In the video, Sean describes his loathing of concrete, a loathing I share. I haven't laid or jackhammered concrete professionally for over 20 years, but I remember how it burns.
Still, as much as I want to see more timber in construction, I recognise that concrete is here to stay, and considering its environmental impacts, we must understand the options for moving towards lower-impact versions.
In this article, the Institution of Structural Engineers provides a one-page overview of their Concrete technology tracker https://lnkd.in/du4ZHENt. It summarises the remarkable advancements in the concrete sector, particularly in developing lower-carbon technologies.
Including:
LC³, a winning combo of calcined clays and limestone fines that can be used today in many parts of the world to make significant carbon savings
Seratech, a manufactured silica cement replacement that captures carbon as it's produced.
Brimstone, a version of Portland cement made from calcium silicate to avoid the chemical emissions related to the usual process.
Cambridge Electric Cement, a process for recycling and reactivating cement from demolition waste
