All that is is old is new again.

Plastics.
Therefore the left wants it outlawed.
“with cement manufacturing accounting for 5 to 7 percent of annual emissions”
This is a one time out gasing. Cement lasts may years without additional out gasing.
Of course the CO2 hysteria is all BS but the first thing that needs to be done to slow the growth of concrete use in this country is to start making road and bridge concrete in the US more durable.
Here in the rust belt winter road salt use destroys concrete and asphalt roads and bridges.
Typical, low cost concrete is porous to water. Water laden with road salt enters the concrete and eventually the salt recrystallizes and cracks the concrete.
Concrete mixtures can be made that are not porous. But they are more expensive. However, the reduction in road maintenance would more that make up the difference in lifetime cost of the road or bridge.
Just stopping the use of lime stone aggregate in road and bridge concrete would make a huge difference.
Oh, great, now the eco-weenies will be advocating for mud huts and thatched rooftops. I advocate we throw them all in a giant sarcophagus and fill it with Portland cement.
So in other words, concrete feeds plants.
What retarded people we have running around these days scaring folks to death with just bad science, junk science and pseudo science.
CO2 is tree food
Concrete produces tree food
Let the Concrete flow
I suspect that the main problems with concrete is that we haven’t figured out how to make it the way the Romans did that lasts so well, and that we don’t plant enough greenery. The trend of plastering concrete over every possible inch in cities needs to go. It may cut down on upkeep (and reduce the need for workers to perform that upkeep), but the price for that is turning tons of ground into do-it-yourself deserts. We could do better.
For specific building projects, cement is only made once before going into concrete for pours. And once concrete is poured into a building foundation, no further processing or transportation should be needed for that foundation for another hundred years or so if properly cured.
Plastics and other more recently proposed materials are still problematic. Even the longest lasting plastics will age much more quickly under pressure or with year-round solar exposure on the edges of a foundation. Many plastic ramps for auto repairs have collapsed, endangering those who used them. Production processes have have produced flaws. Construction workers wouldn’t always do enough to prevent solar exposure and other problems that would cause accelerated aging. Plastic production would obviously be too centralized (centrally controlled and regulated) and too often involves cancer-causing chemicals such as those in some of the furniture sold in Walmart stores.
Tell them it’s China’s fault and they’ll shut up...
Concrete emits food for trees and plant life. Ergo, concrete is good for trees and the greening of the earth.
God bless concrete!
In Kenya they build their villages with manure. I think that is what the left wants us to do instead.
“It is also the second-largest emitter of CO2”
I thought it was cows, or was it airplanes, or was it cars, or natural gas, or plastic straws...
It emits CO2?????
Ferchrissakes!! It should be eliminated!!! We should live in renewable huts and tents like Mexicans and Africans!!
OMG, libs want us to go back to straw huts... after we pay reparations for the cultural appropriation involved in doing that.
