Rebar is used as a tensioning device in reinforced concrete and reinforced masonry structures holding the concrete in compression.
Concrete is used in building a skyscraper to help make it wind proof and able to support its own weight. The building can also be earthquake safe when rods are put through the concrete to make it stable.
you need to have a ''keyway''---that is a groove in the base concrete,can be cut in if concrete has set,if not set,oil a 2x4lightly(lightly) & imbed it into the base concrete flush.
Yes, so that the concrete doesn't break or split.
yes
yes, that is why they put expansion joints on bridges. (: your welcomeyes, that is why they put expansion joints on bridges. (: your welcome

Yes, they put in metal rods to make sure that the whole model stays together.
Yes actually there have! The concrete used to build the tower could not be poured in the day during summer because of the heat therefore builders had to put ice and pour concrete at night when the air was much cooler
yes you can use a framed floor for a metal shed, however you may want to pour a concrete footer (stem wall) to keep the wood up off the ground, or use concrete blocks to support it. And use pressure treated wood.
As a member of the Chartered Institute of Architectural Technologists I am often asked this question when the surface of someones concrete path or ramp starts to break up. Most builders will use a general mix of concrete for a path or ramp and as soon as people put salt on it in winter will blame the owner as salt will damage general concrete. As it is not unreasonable for people to put salt on an icy path or ramp then the builder should have used a road grade concrete as roads don't generally break up after salting in winter. The concrete mix should be stronger and have a higher water:cement ratio, more cement and less water. Normally builders will work the concrete bringing water to the surface; this leaves a very weak mix on the surface that will break up very quickly. Concrete should not be over worked to leave mini air bubbles in the concrete and to stop water from coming to the surface. In extreme conditions air entrained concrete should be used.
Your question implies that all builders do so. This is incorrect. Builders, as with anyone else sweeten tea to their own preference.
the materials were slabs of heavy metal put together so instead of having to use concrete
builders use a database to know how many bricks they need to put in a house hope this helps KKK xx
It just depends on the kind of rods that you use. Most rods are durable but if you put to much weight on them or if there is a child that finds a way to hang from them, then they might not hold up so well.
In Junior and Senior Infants we got concrete objects to count with.
u cant. it has to stay put up with it.
I watched the builders put down precast on the ground.
