    Cement was invented by the early Roman Empire, back when the Romans had a terrible navy because they were terrified of getting wet, to the point that they turned naval battles into land battles to avoid the water.

    For an empire that was so terrified of water that they could literally turn the ocean into dry land, preventing cement from reabsorbing water was effectively a child’s play application of their advanced technology. In fact, they hated water so much that Roman cement actually got even harder when it was submerged.

    As is well known, however, the secret of Roman cement, like the mysterious Roman language itself, has been lost to time, and so while we can still poorly replicate their technology without fully understanding it, the question of why even inferior modern cement is able to stay hard in the rain is a mystery that will probably never be solved.

      Modern cement isn’t inferior at all and reinforced cement is an extremely advanced technology that enables structures Roman cement could never work for

      Modern cement could also last a lot longer than it already does if the public was willing to pay for it but most projects run at minimal cost

        You can’t reinforce cement - it’s already as hard as we can get it without Roman technology. Are you talking about, like, Roman legion reinforcements? Because I don’t think we’ll master time travel until we at least get usable fusion power online.

        It’s true that it looks like most modern public projects are underfunded, but that’s mostly because all roads already lead to Rome so most of the cement work is already done for us.

            Unfortunately, the only cement mix we have is the bastardized one handed down to us from Emperor Concretius, but that dates from after Rome had become a sea power, and consequently lost their ability to maintain their characteristically hard public erections.

            And we’re lucky to even have that! While it would certainly be nice to have the ability to bless our erections with the near-supernatural potency of our forebears, I highly doubt that we’ll ever be able to get as hard as the Romans were in the foreseeable future.
