There are times, when a structure is showing signs of distress, and at such times one of the first things that engineers do is check on the position of the rebar, as any shift from previously designed parameters can lead to weaker structures.

Location of rebar in a reinforced concrete structure

  1. 1. Concrete has a very high compressive strength compared to its tensile strength which is very low. It is possible to increase this tensile strength by introducing rebar in to concrete to. make a reinforced concrete structure which can then take both compressive and tensile stresses and make for structures that have strength and durability.

  2. 2. Rebar in reinforced concrete needs to be put at very specific locations so that it allows the structure to have the required tensile strength. This is done by using spacers and other devices to lock rebar into the specific required locations, which remain so, even when the fluid concrete is poured into the formwork that makes up the shape of the desired structure. More info on: http://scanconcrete.com.au/concrete-scanning/conduits-and-rebar-location-detection
  3. 3. Rebar is made of steel which is vulnerable to rust from atmospheric conditions. This is why rebar needs to be kept at a certain distance within the concrete to prevent any rust formation. Rust formation can cause rebar to lose its form and strength and thus affect the strength of the reinforced concrete structure. More info on: http://scanconcrete.com.au/concrete-scanning/conduits-and-rebar-location-detection
  4. 4. Quite often it is necessary to create new ducts or holes in a reinforced concrete structure to position services or other utilities. When this requires the concrete structure to be drilled through or partially, it is very important to make sure that any such modification is not hampered by the presence of the rebar. More info on: http://scanconcrete.com.au/concrete-scanning/conduits-and-rebar-location-detection
  5. 5. It then becomes very important to know the exact position of the rebar, so that any drilling or breaking done does not come across a rebar. While this can negate the entire process of installing new utilities, because of this obstruction, any damage to the rebar can severely affect the strength of the structure. More info on: http://scanconcrete.com.au/concrete-scanning/conduits-and-rebar-location-detection
  6. 6. These concrete scanning operations use ground penetrating radar to locate rebar. This allows the exact location for the rebar to be established so that any subsequent operations can avoid damaging them.

  7. 7. There are times, when a structure is showing signs of distress, and at such times one of the first things that engineers do is check on the position of the rebar, as any shift from previously designed parameters can lead to weaker structures.
