why does rebar and remesh make concrete so much stronger?
In: 48
Concrete by it self is very strong when it’s compressed. Look at old Roman structures, the design of the buildings and the large amount of concrete made it so that the material it self only had to worry about compression. The weakness of concrete is its sheer factor. Basically when it gets pulled it starts to crumble. This is where rebar comes in. Steel and other metals have incredibly good sheer capacity but tend to be weaker with compression. This is why we put rebar/remesh in concrete so that they can work together to handle compression forces and sheer forces.
If you are curious on a more in-depth and easy to follow video practical engineering did an incredible video describing the in and outs of concrete.
