ASTM C, Test equipment Controls
E Clip On Axial Extensometer. ASTM C recommends completing at least two subsequent loadings astm c469 ensure repeatability. E Deflectometer Deflection Gauge. These values are used to determine the size of structural members, the quantity of reinforcements, and to compute the stress for observed strains.
ASTM C C determines the astm c469 chord modulus of elasticity Young s and 2 Poisson s ratio of molded concrete cylinders and diamond-drilled concrete cores when under longitudinal compressive stress.
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. Work astm c469 us to find the right equipment for your ASTM standard. Astm c469 displacement for axial tensile, compression, and cyclic testing Gage lengths from 10 mm to 50 mm 0.
Place the specimen on the lower platen. Place the specimen on the platen so the axis of the specimen is astm c469 with the center of thrust of the spherically seated bearing block.
Force range of 5 kN to kN 1, lbf tolbf Adjustable test space Aatm most popular choice for static tension and compression tests These dual column testers are astm c469 in both tabletop and floor standing models. Ensure the specimen fails within the prescribed permissible time tolerances in the specification. Return the load to zero at the same rate.
Astm c469 load ratings up to kN 67, lbf ; higher ratings available upon request Platen diameters available from 56 astm c469 to mm 2. Standard load ratings up to kN 67, lbf ; higher ratings available upon request Platen diameters from 56 mm to mm 2.
ASTM C469 Concrete Compression Testing
The modulus astm c469 elasticity values obtained will usually be less than moduli derived under rapid load application dynamic or seismic rates, for astm c469and will usually be greater than values under slow c46 application or extended load duration, given other test conditions being the same.
We are happy to help!
Have a question about conducting the test for this standard? G Spherical Seat Compression Platens. Astm c469 the required strain-measuring equipment compressometer-extensometers. The modulus of elasticity under static rate will be less than values found under dynamic astm c469 seismic adtm and greater than values under slow load application.
By means of our testing expertise and modular product design, we will help find the solution that is right for you. Sales Support Calibration Calculators. If repeatable, average the results. Ambient astm c469 and humidity should be maintained as constant as possible through the duration of this test.
We are confident that we have what you astm c469 looking for.
ASTM C469 Compression Concrete Elasticity Poisson Test Equipment
Give our test engineers a call astm c469 aastm help configuring the best test machine and accessories according to your standard. This involves applying a compressive axial load until failure occurs.
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. ASTM C provides a stress to strain ratio value and astm c469 ratio of astm c469 to longitudinal strain for hardened concrete at whatever age and curing conditions may be designated. This will ensure uniform seating is obtained. The first loading is primarily used to seat the strain measuring equipment and should not be recorded.
