What timespans are we talking about here? 30 years until reinforced concrete starts failing? 100?
- ska 5y agoAs usual "it depends". Basically rust is the problem, so if you are scrupulous on upkeep (read, spend money) it will last much longer than if not. How long is also enviroment dependents (temperature swings, salt air, emiisions etc. can make it worse)
- stonemetal12 5y agoAbout 100 years is the max life span of reinforced concrete. If not done to a high standard half that.
- renw0rp 5y agoWhat about prefabricated houses in post-communist countries? You definitely can't accuse them of using highest quality materials nor spending loads of money on maintenance, but I haven't heard about major failures and there are probably millions of such blocks of flats out there, built mostly between '60-'80 using a couple of different variations of the technology (some involving pre fabricated pieces of reinforced concrete connected with steel joints). I think they were estimated to last 50 years or so, but there is still large proportion of the population living in such houses in some countries nowadays.
- stonemetal12 5y agoSorry, I only got curious and started looking into it after the condo collapse in Florida. Every reference I can find on the subject says 100 years is the max life span of reinforced concrete. Not being a structural engineer I took it at face value.
