CONCRETE REINFORCEMENT DETAILING REQUIREMENT

Reinforced concrete is a composite material, hence a proper bond between the two materials – concrete and reinforcement – is the first requirement. A minimum length of reinforcing bar is needed to develop the full bond strength between concrete and ...

REINFORCEMENT COVER AND PRE-CONCRETE CHECKS

Reinforcement Cover: It is essential that the steel reinforcement bars are surrounded sufficient impermeable concrete to protect them from corrosion, and to allow the combined strength of the reinforcement and concrete to be effective. ...

CURTAILMENT OF REINFORCEMENT IN FLEXURAL MEMBERS

Curtailment of Tension Reinforcement in Flexural Members To economise the design of a flexural member, the tensile bars are curtailed at the section beyond which it is no longer required to resist flexure. Such curtailed bars are extended for a ...

REINFORCEMENT CUTOFFS AND BEND POINTS

Reinforcement Bar Cutoffs and Bend Points It is common practice to cut or bend main reinforcement in beams and slabs where it is no longer required. But tensile steel should never be discontinued exactly at the theoretical cutoff or bend points. ...

PROTECTION OF REINFORCEMENT AGAINST CORROSION

The protection of reinforcement against corrosion can be done by any of the following method: a) Anticorrosive treatment using acid / alkali / other agents based on CECRI technology (as per IS: 9077). b) Fusion bonded Epoxy coating (as per IS:13620). c) Corrosion ...

TYPES OF RCC BEAMS AND REINFORCEMENT DETAILS

Beam is a structural member that supports the transverse load which usually rest on supports at its end. Girder – is  the term applied  to a beam that supports one or more smaller beam. Beams are classified as: a}  Simple Beam b)  ...

SIZE AND QUANTITY OF REINFORCEMENT FOR BUILDING WORKS

Reinforcement is required for reinforced concrete members such as footings, beams, columns, slabs, lintels etc. Estimation of reinforcement quantity is required prior to tendering stage to calculate approximate cost of project or construction work. Following table gives the estimated quantities of ...

LIST OF IS CODES ON REINFORCEMENT

LIST OF IS CODES ON REINFORCEMENT: 1.  IS:432 – Mild steel & medium tensile steel bars and hard drawn steel wires for concrete reinforcement : Part-II -Hard drawn steel wire. 2. IS:1786 -  Specification for High strength deformed steel bars and wires ...

WELDING OF REINFORCEMENT

Welding of reinforcement bars is a practical means of developing the force transfer required in many connection. The following recommendations should be followed when welding reinforcement to avoid damage to the bars and to provide the required force transfer:Carbon content ...
