compressive strength of concrete machine compressive strength of concrete cubes after 7 days

Compliance With Following International Standards
EN 12390-4, ASTM C39, AASHTO T22, IS : 14858 (2000)
 
Automatic Test Execution
Once the machine has been switched on, the specimen positioned and centered, the only required operations are:
 
· Set test parameters - including load rate
· Press the start button
· The machine automatically starts the rapid approach; switches to the test speed once the specimen comes into contact with the upper platen; automatically release the pressure upon specimen failure
· Save the test including data results and load-time graph (Optional)
· The test execution conforming to Standards can be easily proved.
· Working on 240V, 50-60Hz, single phase.
· Dual stage pump assuring fast piston approach and precise test execution
· Test execution conforming to EN 12390-4, ASTM C39, AASHTO T22
· Controllable pace rate from 1 KN/Sec to 10 KN/Sec.
· Inbuilt graph in the touch screen display.
· Auto stop and auto release after completion of each test.
· Accuracy Class 1 (EN) and Class A (ASTM) starting from 10% of full scale.
· Soft platen-to-specimen contact and smooth load rate control from the very beginning of the ramp
· Allow remote verification of settings and performances. For easy debugging of unexpected malfunctions. Complete IP based controller.
 
Frame
· Four column high stiffness welded frame tested for stability.
· Heavy duty spherical seat in lubricating oil bath, allowing initial free alignment at the initial contact with the specimen and automatic jamming up to the end of test.
 
 
Compression platens
· Series TM-42DA fitted with 240 mm diameter platens, which are suitable for testing cylinders up to dia. 100 x 200 mm, 150 x 200 mm and cubes up to 150 mm.
· Surface hardness of platen is 55 HRC, flatness tolerance 0.03 mm. Traceable certificate of surface hardness available on request.
· Attachment for Paver block testing is available at extra cost.
 
 
Safety features
· Max. pressure valve to avoid machine overloading
· Piston travel limit switch (Extra cost)
· Emergency stop button
