Why Does Concrete Crack?

[@cedarpoplar]

This was of a lot of help. I was trying a way to explain to my ol' lady why concrete cracks and to be cautious about the job being poorly done vs. Just being normal cracking. My mom is very meticulous and cautious about everything that happens. I just wanted to ease up on too much stress. Thank you

What's the solution

[@jimjohnson3762]

Yup, I thought I was adding to much water. I like it soupy so it doesn't dry so fast when working by myself.

[@joherrera841]

Hi! Can you give advise on the micro concrete for flooring in homes? Will this crack too?

[@DiffEQ]

Seriously? This mans job isn't to answer random concrete questions. Especially those that are lacking any sort of details! Look it up. yourself. Ugh. Just how little effort can YOU put into something while asking others to do it for you? We are doomed.

Amazing video 💯💯💯💯💯💌

what to apply on cracking after drying

[@DiffEQ]

Look it up. Concrete doesn't "dry", BTW.

Do a video on why streets warp.

[@jasonh289]

heavy vehicles making sharp turns on pavement not designed for heavy loads.. or damage due to excess water penetration weakening the pavement, basically a garbage truck and warp pavement on a culdesac if its not the correct pavement depth, compaction or has water damage, larger vehicles create a surface twisting of pavement for e.g a semi making a u-turn, the front wheels travel and move fine but the rear wheels move slighlty forward and twist on the spot more.

Good basics. In 3 min, more science please. Improper prep, expanding oxidized rebar etc. You da man, tell us more

look it up

This is BS. My pavers made of "concrete" blocks never crack. They only sunk because the foundation is made poorly.

[@PeterLawton]

The truth is somewhere in between. The pavers never crack because their shape allows for very even curing of the concrete. But sidewalks and driveways are extremely thin compared to the length and width, so it's a real challenge (impractical? impossible?) to get very even curing. And even if it did cure evenly, the flat shape still lends itself putting high stress on the surface. Think of how easy it is to bend a playing card, stretching the surface. But if you try to bend in other directions, it's hard, and that is what is used to build a house of cards.

@@PeterLawton If you have a problem with the thickness, insert wires and metals to hold the weight and serve as a cushion. That's what Japanese engineering to the best. They suffer 8k earthquakes a year.
