Since concrete, by nature, is extremely weak in tension, it becomes significant to use rebars (reinforcement bars) as they increase the concrete’s tensile strength. The material used as rebar is steel because the temperature is as high as the concrete’s temperature. So, as concrete needs to be well-supported by the rebars, selecting the best rebars in terms of quality and strength is a critical decision – and applying different quality tests to it is a must.

Mass Per Metre Run Check
Follow the below-mentioned steps of quality inspection:
- Out of the rebars, cut out a 1-metre rod.
- At least have 4 samples for consideration.
- Calculate the average length of each bar from all four sides.
- Calculate weight/metre for all 4 samples.
- Check whether all the values are within the range of the weight value mentioned in the standard code.
Bend Test
In this test, using a mandrel, the reinforcement bar is bent to 180 degrees. If there isn’t any kind of ruptures, cracks, or fractures on the tension side of the bar, the bar has passed the test.
Rebend Test
The first step to conducting this test is by bending the rebar to an angle of 135 degrees. Then, put the bar in boiling water with a temperature of 100 degrees for half an hour – and then let it cool. Bend the bar to 157.5 degrees and if there is no rupture or fracture kind of cracks, then the bar has passed the test.
