9 Important Concrete Reinforcing Accessories

Reinforced concrete is a widely used composite material made up of concrete and steel. In addition to steel, a few other concrete reinforcing products and accessories are added to the mix, so that it acts as a monolithic unit to hold up the entire structure. They contribute to the tensile strength of

Reinforcing Steel - .

Sidep Ltd is an innovative modern industry for cutting and shaping reinforcing steel bars and concrete reinforcement.It provides speed in construction, economy and above all an integrated solution in the supply, cutting, processing and placement of bars, as required by modern standards and demanding project deadlines today. Reinforcing Steel Placement Handbookreinforced concrete box culvert wall is the vertical reinforcing steel on both sides of the wall. The main reinforcing in a single barrel reinforced concrete box culvert slab is the bottom transverse reinforcing steel. The main reinforcing in a bridge slab supported by beams is both the top and the bottom transverse reinforcing steel.

Reinforcing bar specifications - Concrete Construction

Reinforcing bar identification marks required by ASTM specifications; symbols for the infrequently used rail and axle steel are not shown. Bar identification marks may also be oriented to read when bar is in horizontal position. Note that Grade 60 may be indicated either by the number 60 or by a single continuous line. Grades 40 and 50 are not required to show grade designation. Illustration courtesy Concrete Reinforcing Steel Reinforcing steel in slabs on grade - Concrete compensating concrete demands the use of reinforcing steel so the concrete can expand and con-tract as planned. Eliminate the need for thickened slabs at joints and e d g e s . Reinforcing steel gives slabs on grade adequate strength at the joints. This allows the de-signer to maintain a constant slab depth without thickening at joints or edges.
