ACI 301-10 3.3.1.1, in part, states that reinforcement shall be free of material which could be deleterious to bond.
Some limited testing shows that certain kinds of bond breakers are not deleterious to bond between concrete and steel reinforcement. Other bond breakers (membrane forming types) undoubtedly will interfere with bond, and some materials may result in accelerated corrosion of steel reinforcement.

How do you patch or seal an exposed rebar post tension cable in foundation slab?
Rebar and Post Tension cable (PT) are two entirely different items. Rebar is the static steel bars placed in the concrete while the PT are high tensile strength cables that were placed in concrete than stressed under hydraulic jacking to a tension generally around 2500 to 3500 psi. As a result, the situations for repair are different. The exposed rebar can be cleaned and patched through approved methods. However the PT should be looked at by a professional as it is an integral part of the structure and, as mentioned before, is under tensioned stress. If the exposed rebar is in a PT slab, caution should be used and a professional consulted as well, due the rebar being integrated with the PT.
What are rebar use for?
Rebar locators are used to find exactly where the reinforcing steel is located under concrete in existing materials. They are most often used for renovation or remodeling projects.
Your site engineers prepare bbs in the site they directly give the bbs to the bar benders is this a correct approach?
This is an incorrect approach. The current method is the reason for the steel wastage. The steel saving is left to the hands of Bar Benders and site engineers.A scientifically proven system, to save steel in the construction projects is the need of the hour.Steel saving starts with the Rebar Detailed engineering. This is also called as Rebar Detailing. A professional Rebar Placing drawing and an optimized Bar Bending schedule (BBS) are the targeted output of the Rebar detailing.
What is mean by Rebar detailing?
Rebar detailing is the arrangement of the reinforcing steel in the the concrete structure. it shows the details of the shape, size, number or spacing of bars in any rcc structre. different sections of the structure is taken and the arrangement of the reinforcement is shown in it. the picture below is the detailing of rcc structre
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.
What is rebar detailing?
Rebar Detailing is a procedure of making shop drawings for the steel reinforcement for the development procedure. The Rebar Detailing procedure incorporates the position, bending shapes, amount, description, laps of the reinforcing steel and measurements. The Rebar Detailing Drawings are made to incorporate the separating, area, rebar size and lap of steel. The Rebar Detailing Services includes: Rebar Detailing Services, Rebar Shop Drawings Services, Rebar fabrication Services, Rebar Framing Plan Design, Rebar Structure Foundation, Rebar Pit Design, Rebar Framing Plan, Rebar Beam Design, Rebar Structure Steel Detailing, Structure Foundation Rebar Detailing.

Is plain rebar is banned?
Not to my knowledge. It typically is not used. Instead, deformed bar, bar with ribbing, is utilized for better surface area in which to bond with the concrete in which it is placed.
