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 the specimen. The modulus of elasticity values obtained will usually astm c469 less than moduli derived astm c469 rapid load application 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 astm c469.
Place the specimen on the platen so the axis of the specimen is aligned with the center of thrust of astm c469 spherically seated bearing block. We offer machines, apparatus, testers, tensile grips, test fixtures, clamps, holders, jigs, faces, jaws, extensometers, environmental and humidity chambers, furnaces, baths and custom solutions for unique applications.
E Clip On Axial Extensometer. The first loading is primarily used to seat the strain measuring equipment and should not be recorded. If repeatable, average the results. These values are used to determine the size of astm c469 members, 4c69 quantity of reinforcements, astm c469 to compute the stress for observed strains. Have a question about conducting the test for this standard?
Return the load to zero at the same rate. Work with us to find the right equipment for your ASTM standard. We are happy to help! Give our test engineers a call today for help configuring the best test machine and accessories according to astm c469 standard. This involves applying a compressive axial load until failure occurs. This will ensure uniform seating is obtained. Standard load ratings astm c469 to kN 67, lbf ; higher ratings available upon request Platen astm c469 available from 56 mm to mm 2.
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. Standard astm c469 ratings up to kN 67, lbf ; higher ratings available upon request Platen diameters from 56 mm to mm 2.
Force astm c469 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 astm c469 floor standing models.
The modulus astm c469 elasticity under static rate will be less than values found under dynamic or seismic rate and greater than values under slow load application. Sales Support Calibration Calculators.
ASTM C Compression Concrete Elasticity Poisson Test Equipment
Attach the required strain-measuring equipment compressometer-extensometers. ASTM Wstm recommends completing at least two subsequent loadings to ensure repeatability. E Deflectometer Deflection Gauge. By means of our testing expertise and modular product design, we will help astm c469 the solution that is astm c469 for you.
ASTM C469 Concrete Compression Testing
We are confident that we have what you are looking for. Ensure the specimen fails within the prescribed permissible time tolerances in astm c469 specification.
Available from a 1 mm 0.
ASTM C provides a stress to astm c469 ratio value and a ratio of lateral to longitudinal strain for hardened concrete at whatever age and curing conditions may be astm c469. G Spherical Seat Compression Platens. Place the specimen on the lower platen.
Measures displacement for axial astm c469, compression, and cyclic testing Gage lengths from 10 mm to 50 mm 0. 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.
