Products:
| Concrete Compression Test machine |
| Description | Machines have EN 12390-4, BS 1881:115, ASTM C-39 standarts.
General Properties:
1) Full automatic digital controlled with computer accessibility at the same time. Breaks the sample with the set pace rate via the digital unit or the test software and returns to start position automatically. The pace rate can be set between 0.5- 25kN/min with an accuracy of +/-5%.
2) Testers are manufactured in the range of 300 kN - 5000 kN capacities. The standard models are of 1150
KN,2000 kN and 3000 kN capacity.
3) Suitable for testing 50mm,100mm,150mm and 200mm cube samples as well as cylinder samples with 75-160mm diameter and 150-320mm height.
4) All models have a rapid approach pump unit that enables the piston to rise at a rate of 100-150 mm/min
Until loading start on the sample.
5) Pressure safety valve, piston limit switch, removable front and rear gates are standard in all models.
6) Upper compression platens have ball seating assembly for movement in all models. All compression platens have a surface hardness of 55 HRC.
7) Required distance pieces for vertical test distance and sample dimensions are supplied in all models.
8) Pressure transducer with a sensitivity of % 0.3 is used for load measurements.
9) All models operate with 220-240 VAC,50 60 Hz,1 phase mains power.

| Load And Strain Controlled Concrete Compression Tester |
| Description | En 12390-3, en12390-4 en12390-5, en12390-6, astm c 469, astm c109, astm c 39/39m, astm c 78, astm c 1018, din 1048, en 196 standarts
Can determine secant, tangent ve average elasticity module, calculate poisson ratio, sensitive control of loading and unloding pace rate of both load and displacement with a clossed loop pid controlled system, suitable for fatigue tests such as sinusoidal, triangularandsquare waveformat inconcrete.
The system is using fully automatic plc controlled closed loop pid control.
Pace rate can be controlled in both loading and unloading.
The pace rate can be set both as load and as strain. System is a closed loop pid controlled by usind either load values from transducer or loadcell or by using digital encoder with a sensitivity of 1 micron attached between upper and lower
Platens.
The digital encoder and its apparatus can be dismantled from one frame and installed to another.
Up to 4 different frames of different capacities can be connected to the system. Hydraulic power pack can deliver the oil
To any of the frames chosen from the software automatically.
Hydraulic power pack has the rapid approachpumpas standard on it.
All compression frames has an ball seating assembly of 3 degrees movement. The hardness of the compression platens are 55
Hrc.
Themaximum working pressure of the system is 350 bars.
Removable fiberglass front and rear doors are supplied as standart.
For the load measuremet transducer is used on 300 ton compression frame. On other frames 30 ton,10 ton and 1 ton
Capacity load cells are used to measure the load
300 ton compression frame is suitable for testing 10x10x10cm,15x15x15cm and 20x20x20cm cube and 10x20 cm
(diaxheight) and 15x30cm (diaxheight) cylindrical samples.
30 ton compression frame is suitable for testing 4x4x4cm and 5x5x5cm cube samples.
10 ton flexure frame is suitable for testing 10x10x50cm and 15x15x65cmbeams.
1 ton flexure frame is suitable for testing 4x4x16cm beams.
The software is windows based. |

| Universal testing machinery |
| Description | EN 10002-2 standart
Universal hydraulic tensile test machine is designed to test the ferrous materials for structural values such as
Breaking point, breaking tensile, maximum load and maximum tensile. Apart from tensile tests, universal test machines
Can also be used for standard test such as flexure and compression tests up to the capacity of the device.
Universal test machines are produced in two different models having 40 and 60 ton capacities.
Maximum security is maintained by movement limiters on the lower jaw and piston as well as the safety check valves
On the hydraulic system.
Hydraulic power unit works silently.
0 to 50mmdia samples can be tested with a user friendly jaws that comply with all standards.
Load cell is used for load measurements.
Sample holder jaws are of hydraulic power type.
Strain measurement can be done by the electronic displlacment transducer built in the machine or external
Extensometer fitted to the specimen.
Strain measurements can ben done directly from the extemsometer fitted to the specimen.
Tests can be done fully automatic by computer. Machine make the test with the set pace rate and turns to start
Position automatically.
The distance between the grips can be set by motor driven hand set system.

| Vibro Consistometer |
| Description | En 12350-3; bs 1881:104 standarts
Test appropriate for concrete mixers of low and very low workability.
This is a mechanized variation of the slump test and includes a workability of concrete determination based on the principle of subjecting the concrete to vibration after removal of the slump cone. It is mounted on a small vibrating table that operates at fixed amplitude and frequency. The completion time of the required vibration gives an indication of the concrete workability. The consistometer requires an electrical supply of 50 hz to comply with the tests specified. Comprises of a vibrating table, container, slump cone, graduated rod and transparent plate, tamping rod, timer and small square shovel.
