    I did that exact same work decades ago, just for a few days, it was demanding. The most impressive moment is they put the cables into extreme tension before pouring the concrete.
    Warning lights all over the place and loud horns. Everybody's going in worker's emplacements with thick steel doors, in case of a cable snapping. It's no joke.

      they had laid out cables on friday I accidentally nicked one with a welding stinger over the weekend. I told them about it and they pulled it anyway. It held till the machine was 250' 1/2 way down then it snapped and got balled up in the machine. lmao

      Many horrendous accidents have occurred when tow ropes, tow cables or tow chains snap on vehicles. The stored energy is immense and God help anyone that gets caught in the whiplash.

      I thought it interesting that even after cutting through the pre-stressed cable, it showed only minor shrinkage from the cut surface.

    Quick explaination on curing: Concrete is mixed with water to trigger the creation of crystals between the particles in the concrete which cause it to get hard. Thus, the wetter the concrete, the better it cures. That's also why they cover the slabs with blankets, so they don't dry out. And that's also the reason why you can actually build under-water structures in-place with concrete. Interestingly enough, concrete also binds the water permanently. So when you see concrete, it's actually soaked in water, even though it is dry.

    1. PS 콘크리트라고 부르는 슬래브이다.
    2. 미리 강선을 긴장해서 배치하고 콘크리트를 타설하는 공법이다.
    3. 강선을 자르면 바로 스트레스가 도입되기 때문에,
    "프리텐션" 공법이라고 부른다.
    반면,
    콘크리트를 먼저 양생한 다음,
    나중에 강선을 강하게 긴장해서 스트레스를 주는 것을,
    "나중 스트레스" 즉,
    "포스트 텐션" 이라고 부른다.
    4. 위 영상의 경우에는,
    강선이 아래 쪽에 배치되어 있다.
    때문에,
    강선에 의한 압축력 때문에,
    슬래브가 위로 솟아 오른다.
    통상,
    PS 콘크리트 빔이나 슬래브는,
    휨 모멘트 때문에 이렇게 중심축에서 벗어나게 긴장재를 배치하고,
    그 결과,
    프리스트레스를 도입하면,
    빔이나 슬래브가 위로 솟구치는 현상이 생긴다.
    5. 너무 강하게 긴장하면,
    솟구치다가 콘크리트 중앙부분이 똑 부러져버린다.
    물론,
    애초 설계때부터,
    이렇게 프리 스트레스를 도입할 때의 모멘트로 인한 파괴가 되지 않도록 한다.
    6. 위로 솟음이 발생한 빔이나 슬래브는,
    사실 중앙부의 인장 응력이 파괴에 가까운 상태이다.
    따라서,
    "내가 많이 들어 봤어!" 이러면서,
    위 영상의 슬래브나 빔의 한 가운데 줄 하나 걸치고,
    크레인 등으로 들어 올리면?
    바로 뚝 부러져버린다!

      One of the advantages of tension before pouring the concrete is that when the external tension is released, the steel expands and clamps itself.
