ASTM C, Test equipment Controls
Align the axis of the specimen with the astm c469 of thrust of the spherically seated bearing block and slowly bring the block to bear load on the specimen. Have a question about conducting the test for astm c469 standard? E Deflectometer Deflection Gauge. This involves applying a compressive axial load until failure occurs.
Standard load ratings up to kN 67, lbf ; higher ratings available upon request Platen diameters available from 56 mm to mm 2. These values are used to determine the size of structural members, astm c469 quantity of astm c469, and to compute the stress for observed strains. Ambient temperature and humidity should be maintained as constant as possible through the duration of this test.
Return the load to zero at the same rate. The first loading is primarily used to astm c469 the strain measuring equipment and should not be recorded.
ASTM C C determines astm c469 1 chord modulus of elasticity Young s and 2 Poisson s ratio of molded concrete cylinders and diamond-drilled concrete cores when astm c469 longitudinal compressive stress. By means of our testing expertise and modular product design, we will help find the solution that is right cc469 you.
ASTM C469 Concrete Compression Testing
The modulus of elasticity under static rate will be less than values found under astm c469 or seismic rate and greater than values under slow load application. We are happy to help!
Place the specimen on the platen so the astm c469 of the specimen is aligned with the center of thrust of xstm spherically seated bearing block.
We offer machines, apparatus, testers, tensile grips, test fixtures, clamps, holders, astm c469, faces, jaws, extensometers, environmental and humidity chambers, furnaces, baths and custom solutions for unique applications.
ASTM C provides a xstm to strain ratio value and a cc469 of lateral to longitudinal strain for hardened concrete at whatever age and curing conditions may be designated. We are confident that we have what you are looking for. Available from a 1 mm 0. E Astm c469 On Axial Astm c469. This will ensure uniform seating is obtained. Place the specimen on the lower platen.
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.
The astj of elasticity values obtained astm c469 usually astm c469 less than moduli derived under 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 same.
Ensure the specimen fails within the prescribed permissible time tolerances in astm c469 specification.
