Re: Measurement of Concrete Reinforcing Bar Length

[Subject Prev][Subject Next][Thread Prev][Thread Next]
Mark,

There is an equipment called PROFOMETER which can measure:

   - cover to rebar,
   - rebar diameter, and
   - possibly number & length of rebars., but Iam
     not sure about this third aspect of its
     capacity.

I suggest you contact the following internatinal equiment/instrument
manufacturers, which might be able to help you in this regards:

   -  ELLE INTERNATIONAL (U.K, USA & France)
   -  CONTROLS (Italy)
   -  JAMES INSTRUMENTS (USA)

You can visit their web sites as well to find out more about this.

Do any of you have knowledge of a means to determine the length of
reinforcing steel bar when only one end is exposed or accessible?
Preferably a technique or technology that allows for measurement through
standard radius bends, in bar lengths up to standard mill lengths.  I
assume it will be necessary to have one square cut end exposed.

I was originally thinking of some of the ultrasonic bolt measurement
technology, but it is overkill in precision, and generally limited in
application to shorter lengths.

Thank you
