(Trainee BTW) At work today I got asked to do some calculations for reinforced concrete. It was a slab approximately 9x3 metres and had a mesh rebar … It came to aboout 180 KG and was about 315m long. I couldn't for the life of me find anything on the internet about how to work out the Kg/m cubed?
American Concrete Institute 531, Building Code Requirements for Concrete Masonry Structures Magnetic methods, such as a cover meter, have been used to successfully locate reinforcing bars in Then insert 6-foot-long vertical rebars in the cores, properly positioning them in the rebar chairs.
A rebar locator looks similar to a stud finder and has a flat side that sits flush against the concrete so The rebar looks like curves on the chart due to how the radar waves bounce off of them. Rebar rods are usually installed in a grid-like pattern, so make sure you always locate it from each direction.
Frequently, rebar and poured concrete are used to reinforce the strength of concrete blocks. Here you will find information on how to put rebar columns You will need to have your local utility company come out to locate any underground power lines to ensure that they are not damaged or

Concrete and reinforced concrete are two completely different materials. So yes, the placement of rebar is absolutely critical for this and several other reasons. i am curious how many have demo'ed a pre-stressed or post stressed structural concrete member? let me tell you from personal
Is there a simple way to locate rebar in existing concrete? I need to drill a few holes in a concrete slab (basement), and the last time I did that, I kept hitting rebar. They work great for finding the rebar in existing concrete. The cheap ones are almost worthless for actual stud location, but are fab
The location of rebar in reinforced concrete is an important examination item in the field of architecture. As a kind of non-destructive detection method, susceptibility of rebar is measured on the surface of reinforced concrete with susceptibility meter. Meanwhile，the correlation imaging

Concrete Scanning for Rebar Mapping at Norfolk International Airport - Norfolk, VA. A contractor out of Sturtevant, WI, called Ground Penetrating Radar Systems to locate the rebar within the airport where they were going to be installing anchors into the slab on the second floor, and did not want
Rebar, also known as reinforcement steel and reinforcing steel, is a steel bar or mesh of steel wires used in reinforced concrete and masonry structures to strengthen and hold the concrete in tension. To improve the quality of the bond with the concrete, the surface of rebar is often patterned.
Concrete Inspection Information. GPR to Locate Rebar. Concrete and construction professionals use ground penetrating radar to safely locate structural reinforcement within poured concrete prior to drilling, cutting or coring.
Learn about how to use steel rebar for concrete footings at When rebar is placed within a footing, it should be completely encased in concrete by a minimum of 3 inches on all sides. When rebar is allowed to project out of the footings, it is susceptible to more rapid corrosion.
A cover meter is an instrument to locate rebars and measure the exact concrete cover. Rebar detectors are less sophisticated devices that can only locate metallic objects below the surface. Due to the cost-effective design, the pulse-induction method is one of the most commonly used solutions.
Find out how to locate rebar in concrete with Xradar. Many contractors choose to neglect a thorough scan of concrete before cutting and coring in order to save time. However, this can have major consequences that are both costly and potentially hazardous.
