Concrete is the second-most used material on earth. It is also the second-largest emitter of CO2, with cement manufacturing accounting for 5 to 7 percent of annual emissions. The continued popularity of concrete as a material of choice in the design and construction industry, coupled with increasing unease of the environmental consequences, has put concrete firmly in the spotlight of innovation and experimentation. As a result, designers, architects, and researchers around the world are generating multiple visions for what the future of concrete in architecture could look like.
Concrete has been a material of choice for architects and builders for thousands of years, with the earliest known use dating from Syria and Jordan in 6000BC. Its low cost, versatility, fast application, and sheer familiarity to those involved in using it means that roughly 22 billion tons of concrete are poured every year. According to a recent BBC study, production of cement has increased thirtyfold since 1950, and a further fourfold since 1990, driven in part by postwar building in Europe, and building booms across Asia from the 1990s onwards. It is predicted that to keep pace with demands in South East Asia and sub-Saharan Africa, cement production may have to increase by 25% by 2030.

So cancel all everything and then they’ll be happy?
Communists LOVE concrete! So another issue where we’ve come full circle I guess. Commies and concrete, except for commies and carbon now conflicting.
First we will tear down the roads and homes and schools and factories of the peasants. Only after that will we deal with the concrete problems of the communist elites in the cities.
Concrete will be around as long as cheap illegal labor is available to work it.
Hopefully one day we will replace concrete buildings with buildings made from plastic recycled from the Pacific trash island. /s
Oh, of course. That goes without saying!
That’s funny. I tell my lefty acquaintances, “when the socialists get their way “I’m going in to the prefabricated mud hut business”. They look at me like I have 3 heads.
That’s because they’re too intellectually bereft to connect the dots. They’re lemmings. Drone worker ants. No sense of self or individuality. They chirp off the Leftist talking points that make themselves feel good, like magpies. Do you really think what they believe is for ‘the good of the people’? They don’t really give a flying f**k at a rolling donut about their fellow travellers unless there’s a common goal involved. Give them what they want, and they’ve already moved on to the next windmill to tilt.
I've believed this for years. It's how Democrats get union votes, too.

Of course they don’t. When I confront them about their own greed and hypocrisy I always get the same answer, “I’m weak”.
Hard to beat concrete for strength/durability/cost - I once hear an old guy who had been in the business for over 50 years remark that concrete aged and got stronger for the 1st hundred years and then slowly deteriorated for the next hundred years...I have no idea if that’s true but have had a hell of a time busting up some 25 year old concrete slabs...even w/o rebar or fibers holding them together.
More climate radicalism.
It's a hoax why even play that game? "Out gasing" is used by climate radicals.
CO2 levels are at an almost historic low.
All concrete will cure under water. Temperature is the main factor in how long it takes for the concrete to cure. Water will be a giant heat sink and slow the curing rate down considerably, but it will cure eventually.
In Kenya they build their villages with manure. I think that is what the left wants us to do instead.

Hmmmm...sounds like a plan. ;-)
“Out gasing” is used by climate radicals.”
It is also used by people with allergies caused by being near some uncured products like fresh concrete.
Sod... The elites at the UN want us all back into mud huts... They, of course, have other plans for themselves..
A friend of mine spent a year in the Stans commanding a unit that spent much of its time purchasing concrete and gravel for Afghanistan.
He said it was his first deployment without a gun and with more business suits than uniforms
I know the drill. I was just commenting on the unseen carbon footprint of concrete. Most jobs are relatively small, and therefore require a plant set up within an hour or two of the site, which means a lot of plants, and a lot of trucks. Mixing your own in remote locations is doable, but you still have to get the heavy materials to the site.
What I find most interesting is "aerated concrete." I've also heard it called autoclave concrete.. If I were young and ready to build again, that would definitely be my first choice..
