Compression Testing Machine for Concrete Manufacturer,Supplier and Exporter in India
Product Code : EL-CACTE-9444
Jlab Export is a leading Compression Testing Machine for Concrete Manufacturer,and suppliers in India
This hand-pumped machine crushes concrete specimens up to 1000 kN and needs no power supply. The load shows on a single 150 mm Bourdon tube load gauge that reads in 5 kN steps and has a maximum load pointer. The gauge is calibrated against proving rings.

Concrete Mix Practicals with Cube Tests
In a college concrete lab the work starts with a trial mix in a Laboratory Concrete Mixer. Students check workability with a Slump Test Apparatus, then fill Cube Moulds in layers and compact each one. Next day the cubes are stripped and cured in water until they are tested.
At 7 and 28 days the cubes come out of the tank, are wiped surface dry and crushed one at a time. Students pump at a steady rate so the needle climbs evenly, then read the failure load from the maximum load pointer. Three cubes per age are averaged and compared with the target strength of the mix.
Frequently Asked Questions
What does the maximum load pointer do?
The main needle pushes it round, and it stays at the highest load reached. When the cube fails, the main needle falls back but the pointer stays at the failure load, so the reading can be taken after the test. Reset it against the needle before the next cube.
What does a 5 kN least count mean for strength?
The gauge reads in 5 kN steps. On a 150 mm cube, with a loaded area of 22,500 mm², one step is about 0.22 N/mm². That is small compared with the strength of normal concrete.
How much is 1000 kN in tonnes?
1000 kN is about 102 tonnes of force. On a 150 mm cube it equals a stress of about 44 N/mm², so the machine covers 150 mm cubes up to roughly that strength.
What do vertical daylight and horizontal clearance mean?
Vertical daylight is the 310 mm opening between the platens, which limits specimen height. Horizontal clearance is the 260 mm adjustable clear width in the frame, which limits specimen width. The specimen sits on the 240 x 165 mm platens.
