Description
The Liya Test Automatic double testing chamber compression and flexure testing machines have been designed for reliable and consistent testing of mortar samples. These compression and flexure testers are the results of continuous applications and research studies to upgrade the machines with the latest technologies and conform the current standards EN 196-1, 459-2, 1015-11, 13454- 2; ASTM C 109, C348, C349 in terms of its technical properties taking into account client requirements by using suitable accessories. These machines also meet the requirements of CE norms for safety and health of the operator.
Tests can be performed by either on Control Unit or on a computer with using Software which is provided free of charge with the machines. The advantages of performing tests on computer with using Software, such as reporting, graphical output, etc. can be seen in detail at the software pages.
The automatic cement compression and flexure testing machines allow less experienced operators to perform the tests. Once the machine has been switched on and the specimen is positioned and centered by the help of centering apparatus. The only required operations are;
- Setting test parameters, including pace rate (only required when the specimen type is changed.)
- Choosing the compression or flexure frame by using the changeover valve.
- Pressing the START button on the control unit.
- The machine automatically starts the rapid approach; switches the test speed after 1% of the load capacity of the machine and stops once the specimen failure.
- Automatically saves the test parameters and test results.
The automatic cement compression and flexure testing machines consist of very rigid two column single or double chamber frames ( see table) and automatic hydraulic power pack with Control Unit
Main Features
- Pace rate control from 50 N/sec (flexture) to 2,4 kN/sec (compression)
- Class 1 (EN ISO) and Class A (ASTM) starting from with the 1 %. for 250 kN and 15 kN capacity
- Supplied with factory calibration certificate for load measurement
- Closed loop control with automatic test procedure.
- Can make the test with load control
- Stand-Alone control or computer control
- Free of charge software for the tests
- Load measurment with the load cell.
- Hydrolic pump with dual stage for rapid approach
- Piston return at the end of test automatically
- Adjustable rapid approach rate
Control Unit for Automatic Compression/Flexure Testing Machines
Control Unit is designed to perform automatically compression, flexure and splitting tensile strength tests of construction materials such as cement mortar, concrete, masonary units/blocks by controlling the automatic compression / flexure testing machines.
All the operations of are controlled from the front panel touch screen display.
Control Unit has easy to use menu options. It displays all menu option listings simultaneously, allowing the operator to access the required option in a seemless manner to activate the option or enter a numeric value to set the test parameters. Digital graphic display is able to draw real-time “Load vs. Time”, or “Stress vs. Time” graphics
Software for Automatic Compression / Flexure Testing Machines
Software provides to perform automatically compression, flexure and splitting tensile strength tests of construction materials such as concrete, cement mortar, masonary units/blocks by controlling the automatic compression / flexure testing machines.
The advantages of performing tests on computer with using Software, such as reporting, graphical output, etc. can be seen in detail at the pages of Software for Automatic Compression / Flexure Testing Machines.
Safety Features
- Maximum pressure valves to avoid machine overloading
- Piston travel limit switch
- Emergency stop button
- Software controlled maximum load value
- Removable transparent front-rear safety doors (Should be factory installed and ordered separately)
