19mm = 2.235 kg/m Equal to US #6 = 1.502 lbs/ft
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.
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.
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.
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

Unit weight of 36mm rebar is 7.99 kg per meter
3.4 lbs/ft or 5.06 kg/m
Calculate the length of steel you are going to use the building and muliply the length with unit weight of the steel.ex: 12 m 25mm steel weight is12 x 3.85 =46.2 kg3.85 kg/m is the unit weight of 25mm bar
