The first loading is primarily used to seat the strain measuring equipment and should not be recorded.
We are happy to help! These astm c469 are used to determine the size of structural members, the quantity of reinforcements, and to compute the stress for observed strains.
ASTM C469 Compression Concrete Elasticity Poisson Test Equipment
The modulus of elasticity under static rate will be less than values found under dynamic or seismic rate and greater than values under slow load application. E Clip On Axial Extensometer. Standard load ratings up to kN 67, lbf ; higher ratings available upon request Platen diameters astk from 56 mm to mm 2. We offer machines, astm c469, testers, tensile grips, test fixtures, clamps, c46, jigs, faces, jaws, astm c469, environmental and humidity chambers, furnaces, baths and custom solutions for unique applications.
ASTM C recommends completing at least two subsequent loadings to ensure repeatability.
Ambient temperature and humidity should be maintained as constant as possible through the duration of this test. Attach the required strain-measuring astm c469 compressometer-extensometers.
Return the load to zero at the same rate. G Spherical Seat Compression Platens. ASTM C provides a stress astm c469 strain astm c469 value and a ratio of lateral to longitudinal strain for hardened concrete at whatever age and curing asgm may be designated.
This will ensure uniform astm c469 is obtained. Work with us to find the right equipment for your ASTM standard. Force range of 5 kN to kN 1, lbf tolbf Adjustable test space The most popular astm c469 for static tension and compression tests These dual column testers are available in both tabletop and floor standing models.
ASTM C469 Concrete Compression Testing
Place the specimen on the platen so the axis of the specimen is aligned with the center of thrust of the spherically seated bearing block. The modulus of elasticity values obtained will usually be less than moduli derived under rapid load astm c469 dynamic or seismic rates, for exampleand will usually be greater than values under slow load application or extended load duration, given other test conditions being the same. We are confident that we have what you are looking for.
Astmm our test engineers a call astm c469 for astm c469 configuring the best test machine and accessories according to your standard.
ASTM C Concrete Compression Testing – ADMET
Align the axis of the specimen with the center of thrust of the spherically seated bearing block and slowly bring the block to bear load on astm c469 specimen. ASTM C C determines the 1 chord modulus of elasticity Young s and 2 Poisson s ratio of molded concrete cylinders and diamond-drilled concrete cores when under longitudinal astm c469 stress.
E Deflectometer Deflection Gauge. If repeatable, astm c469 the results. Sales Support Calibration Calculators.
Standard load ratings astm c469 to kN 67, lbf ; higher astm c469 available upon request Platen diameters from 56 mm to mm 2. Ensure the specimen fails within the prescribed permissible time tolerances in the specification.
Available from a 1 mm 0. Astm c469 means of our testing expertise and modular product design, we will help find the solution that is right for you. Have a question about conducting the test for astm c469 standard?

This involves applying a compressive axial load until failure occurs. Place astm c469 specimen on the lower platen. Measures displacement for axial tensile, compression, and cyclic testing Gage lengths from 10 mm to 50 atsm 0.
