The machine is used to test the
flexural strength of mortar and concrete specimens. Testing flexural
strength of concrete beams is very important during all types of
construction.
Types
There are mainly two types of Flexural Testing Machines :
- Hand operated
- Electrically operated
Salient Features
- The hand operated flexural testing machine consists of a hand
operated load frame.
- There are two rollers in the lower platen, the distance between
whom can be adjusted.
- The center to center difference between the two rollers varies
according to size of the beam.
- There is a pressure gauge fixed on the load frame to indicate
load.
- There is also a small pumping unit attached to the load frame.
- The hand operated machine is light weight and can also be used in
field laboratory.
- The electrically operated machine has a separate electrically cum
hand operated pumping unit housed in a cabinet.
- The machine has a motorised load frame, with a constant rate of
strain to supply load on the specimen.
- In the electrically operated machine, there is a pressure gauge,
an on/off switch and a slow/fast level to control rate of loading.
All these are attached to the front panel of the pumping unit.
- A micro switch and relay are also attached inside the pressure
gauge to protect the unit from over loading.
