Product Description
1.Applications
This concrete static modulus of elasticity compression testing machine is to determine static modulus of elasticity of molded concrete cylinders and diamond-drilled concrete cores when under longitudinal compressive stress.
2.Size of concrete specimens for compression modulus of elasticity test
Concrete cubic specimen: 150X150X300mm, 100X100X300mm, 200X200X400mm
Cylindrical concrete specimen: φ150X300mm, φ100X200mm, φ200X400mm
3.Brief introduction of concrete modulus of elasticity test procedure
3.1 Use at least two companion specimens to determine the compressive strength in accordance with test method ASTM C39/C39M prior to the test for modulus of elasticity.
3.2 Place the concrete specimen, with the strain-measuring equipment attached, on the lower platen of the testing machine. Carefully align the axis of the specimen with the center of thrust of the spherically-seated upper bearing block. Note the reading on the strain indicators. Before applying the load on the specimen, tilt the movable portion of the spherically seated block by hand so that the bearing face appears to be parallel to the top of the test specimen based on visual observation.
3.3 Load the specimen at least three times. Do not record any data during the first loading. Base calculations on the average of the results of the subsequent loadings.
3.4 Apply the load continuously and without shock. Load the specimen until the applied load is 40% of the average ultimate load of the companion specimens.
3.5 During the first loading, observe the performance of the gauges. Correct any attachment or alignment defects that may be causing erratic readings prior to the second loading. For the second and subsequent loadings, obtain each set of readings as follows: record, without interruption of loading, the applied load and longitudinal strain at the point when the longitudinal strain is 50 microstrain and when the applied load is equal to 40% of the ultimate load of the companion specimen.
3.6 Upon reaching the maximum load, except on the final loading, reduce the load to the zero at the same rate at which it was applied.
4.Software for concrete static modulus of elasticity compression test
4.1 Windows based interface, easy and fast to reach different functions, suitable for most of operators using habits.
4.2 The software provides multi functional control mode: Load (stress) control; Displacement (Stroke) control, Strain (Deformation) control, Load keeping, Displacement keeping, Customized programming control ect.
4.3 In stroke control mode, operator can define customized test speed to conform to different test standard. Preset limit position and return position will secure the safety and return the crosshead automatically after test finished. In program control mode, the testing machine is controlled by conditional programs, operator can input each condition to regulate test process, and software can realize constant parameter control through this function.
4.4 Realize the testing diagram online display and reproduction.
4.5 Zoom in or out the test diagram at any place with any rate.
4.6 Auto suit the diagram according to display resolution
4.7 Coordinates point tracing to check the test results in each point
4.8 The software provides different way to create test report: Single material test report, Batch material test report, Customized test report, Coordinates point test report
4.9 test curves: load-time, extension- time, load-displacement, load-extension, stress-strain,etc
5.Relative test method
GB/T 50081 standard for test method of mechanical properties on ordinary concrete
ASTM E74 practice of calibration of force-measuring instruments for verifying the force indication of testing machine
ASTM C469/C469M Standard Test Method for Static Modulus of Elasticity and Poison's Ratio of Concrete in Compression
ASTM C39 Standard Test Method for Compressive Strength of Cylindrical Concrete Specimens
