Ok for starters how about we stop treating concrete like shit and respect it for the powerful material it is, and stop fucking it up by placing iron rebar in it. If you make your whole building out of concrete and rebar to compensate for the shitty tension abusing design it is, on paper it seems cheaper than making a pure concrete compressive building. HOWEVER, this is only if you make the short-sighted view of fucking over future generations, because that building will decay and wither, and it turns out the cost of making the same building twice is more than the cost of making the building right once. Concrete utilises sand which is an increasingly scarce resource - it is not renewable, in the sense that it cannot be made without horrendous expenditure of energy resources, and usable sand for concrete is not a resource we can afford to readily deplete. Once it has been turned into concrete, you're not turning it back into sand without leaving it in the ocean for a million years.
Make a single concrete building. No iron rusting and cracking inside it. It will last like a roman building; there isn't really anything too special about roman concrete, our concrete today is also good, but concrete can never last long if you put rusting/expanding metal inside it. Really all buildings should try in so far as possible to not violate the same material rule. It's why there are houses made of nought but red brick or houses made of nought but wood that are older than the United States, because same material rule goes a long way to avoiding moisture trappage.
And you know what, whilst I'm shilling for concrete appreciation as an expensive resource and not a cheap resource, why stop there?
Fucking plastic. Plastic is considered one of the cheapest and most disposable resources we have, and yet it comes from a non-renewable resource and has physical properties that are downright miraculous. On its properties alone, plastic should be the substance of our most essential of stuff, not the most frivolous. SPREAD THE GOOD WORD
APPRECIATE CONCRETE
BE GRATEFUL FOR PLASTIC
REMEMBER SAND
