It depends on the structural element in which the bars are being placed. In a footing, it is 3" clr of the bottom of the ftg. In a slab, it can be centered in the slab or located towards the top or bottom. Details and sections shown on the structural drawings or general notations or specifications by the engineer of the projects record should clarify the exact location the bar is to be placed.

Why do builders put metal rods in concrete?
Rebar is used as a tensioning device in reinforced concrete and reinforced masonry structures holding the concrete in compression.
How do you strengthen concrete with reinforcing rod?
Rebar is used to strengthen concrete because of its strength and flexibility. In order for these rods to work, there must be ample space between the rebar and the edge of the concrete piece.
What is the difference between lap splice length and development length for rebars?
The difference between the two is in the application. A development length is the amount of rebar length that is needed to be embedded or projected into concrete to create a desired bond strength between the two materials. The lap splice length is the length two rebar pieces must overlap and be tied together to create a bond as if there was no break and the run is "continuous". So simply put, development is rebar to concrete, splice is rebar to rebar. The lengths of both splice and development do vary. They are dependent upon different factors. These include but are not limited to concrete strength, rebar size, rebar coating and concrete cover or clearance. So when you see a chart on one project, it can differ from another for these reasons.

How much steel required for 1meter cubic of conceret?
It depends on how much rebar you're willing to lay down, in earthquake prone areas and structural concrete you'll generally see a lot of rebar, in just normal paver concrete you may not see any. Rebar is used to give concrete flexibility without brittleness so it really depends on the use of the concrete.
Is epoxy required in rebar connections?
Epoxy is not required in rebar connections as concrete and wire are used to hold it in place. Rebar is a reinforcement place inside masonry structures to provide increased strength.
