RE-BAR AND STEEL SECTIONS
[EIRI/EDPR/1631] J.C. 435US$
INTRODUCTION
Reinforcing steel bars are used to help concrete withstand tension forces. Concrete by nature is sufficiently strong to compression forces, although tension forces can crack concrete. Deformed re-bars on reinforcing steel was made a standard requirement since 1968, however, plain re-bars are also used in situations where the reinforcing steel is expected to slide as usually installed in highway pavement and in segmental bridges. The deformed patter on a rebar will help the concrete to adhere to the reinforcing steel surface. The pattern on a deformed bar is not specified, however, the spacing, and the height of the ‘bumps’ is regulated.
1. Welded Wire Fabric
Welded wire fabric is made from a series of steel wires arranged at right angles and electrically welded at all steel wires crossings. Welded wire fabric, also known as WWF, can be used in slab-on-ground slabs, where the ground has been well compacted. A heavier fabrication of welded wire fabric can be used in walls and structural floor slabs. This is commonly used in road pavements, box culverts and drainage structures, and small concrete canals.
2. Sheet-Metal Reinforcing Bars
Sheet-metal reinforcement is commonly used in floor slabs, stairs and roof construction. Sheet-metal reinforcing is composed of annealed sheet steel pieces bent into corrugations about 1/16 inch depth, with holes punched at regular spacing.
3. Stainless Steel Reinforcing Bars
Stainless steel can be used as an alternative reinforcing steel bars with carbon steel reinforcement. Using stainless steel reinforcing bars will not create galvanic corrosion, and can be a cost-effective solution in areas subject to corrosion problems, or where repair is difficult and expensive.
4. Expanded Metal and Wire Mesh Reinforcement
Expanded metal or wire mesh reinforcement is also another good reinforcement product for concrete. Expanded metal is made by shearing a sheet of steel into parallel lines and the expanded to form a diamond shape or square shape between each cut. Expanded metal is commonly used as reinforcement in areas where great thickness of plaster is required, or to reinforced light concrete construction. Wire mesh reinforcement can be used on sidewalks, small concrete pads or walkable surfaces that do not receive high live nor load charges.
