The modulus of elasticity values obtained will usually be less than moduli derived under rapid load application dynamic astm c469 seismic rates, for exampleand will usually be greater than values under slow astm c469 application or extended load asstm, given other test conditions being the same.
ASTM C469 Concrete Compression Testing
Sales Support Calibration Calculators. Astm c469 the specimen fails within the prescribed permissible time tolerances in the specification. The first loading is primarily used to seat the strain measuring equipment and should not be recorded. Work astm c469 us to find the right asgm for your ASTM standard.
ASTM C C determines the 1 chord modulus of elasticity Young s and 2 Poisson s astm c469 of molded concrete cylinders and diamond-drilled concrete astm c469 when under longitudinal compressive stress. If repeatable, average the results.
Asmt our test engineers a call today for help configuring the best test machine and accessories according to your standard.
This will ensure uniform seating is obtained. This involves applying a compressive axial load until failure occurs.
ASTM C, Test equipment Controls
By means of our testing expertise and modular product design, we will help find the astm c469 that is right for you. Force range of 5 kN to kN 1, lbf tolbf Adjustable test space The most popular choice for static tension and compression tests These dual column testers are available in both tabletop and floor standing models.
Astm c469 modulus of elasticity under static rate will astmm less than values found astm c469 dynamic or seismic rate and greater than values under slow load application. Measures displacement for axial tensile, compression, and cyclic testing Gage lengths from 10 mm to 50 mm 0.
Place the specimen on astm c469 lower platen. ASTM C provides a stress to strain ratio value and a ratio of lateral to longitudinal strain astm c469 hardened concrete at whatever age and curing conditions may be designated.
Available from a 1 mm 0.
ASTM C469 Compression Concrete Elasticity Poisson Test Equipment
Ambient temperature and humidity should be maintained as constant as possible through the duration of this test. We offer machines, astm c469, testers, astm c469 grips, test fixtures, clamps, holders, jigs, faces, jaws, extensometers, environmental and humidity chambers, furnaces, baths and custom solutions for unique applications.
Standard load ratings up astm c469 kN 67, lbf ; higher ratings available upon request Platen diameters available from 56 mm to mm 2. ASTM C recommends completing at least two subsequent loadings to ensure repeatability.
E Clip On Axial Extensometer. Standard load ratings up to kN 67, qstm ; higher ratings available upon request Platen diameters from 56 mm to mm 2.
We are happy to help! Attach the required strain-measuring equipment compressometer-extensometers.
We are confident that we have what you are looking for. Have a question about conducting the test for this standard? 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. Return the load to zero at the same rate. G Spherical Seat Compression Platens. E Astm c469 Deflection Gauge. 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 the specimen.
These values astm c469 used to determine the size of structural astm c469, the quantity of reinforcements, and to compute the stress for observed strains.
