    reading in slow regard for silent things will be infinitely better if you
    read the rest of the kingkiller chronicles as well

    I’m surpized you didn’t mentioned the problems with Concrete. Like how it
    can crumble after time.

    Fun fact, if you soak cured concrete, it gets stronger.

    I feel like I’m back in my materials class haha. Nice work!

    Was the picture of the calcium silicate hydrate crystals taken using an
    electron microscope?

    As a civil engineer I feel obligated to like and share this video

    For someone who’s interested in concrete and the chemical level of
    reactions, but with no chemistry background, what type of chemistry courses
    would you advise them to take to ease their entrance to the chemistry of
    concrete? (They have a background in structural engineering)

    that’s what i do to my hair. i dont dry it. it just settles.

    A cement is only 90% set after a year. The cracks are a good sign actually.
    Because it means the plaster is more and more hardened.

    Enter, Epoxy.

  14. CrispyChicken44 says:

    If concrete gets stronger over time, then why do old civilization’s
    buildings crumble and become so fragile? Even with weathering effects,
    isn’t that sentence false? I’m confused.

    Ooo, I just thought of a really good vid topic: boomerangs.

    wow! didn’t know pantheon was made of cement… I mean I thought cement
    hadn’t been invented back then.

    the way you over-enunciate is painful to listen to
