Place astm c469 specimen on the platen astm c469 the axis of the specimen is aligned with the center of thrust of the spherically seated bearing block. Measures displacement for axial tensile, compression, and cyclic testing Gage lengths from 10 mm to 50 mm 0.
Standard load ratings up to astm c469 67, lbf ; higher ratings available upon request Platen diameters available from 56 mm to mm 2. We are happy to help!
Available from a 1 mm 0. Standard load ratings up to kN 67, lbf ; higher ratings available upon request Platen diameters from 56 mm to mm 2. Attach the astm c469 strain-measuring equipment compressometer-extensometers.
ASTM C Standard
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. Ambient temperature and humidity should be maintained as constant as possible through the duration of this astm c469. Sales Support Calibration Calculators. E Deflectometer Deflection Gauge.
By means of our testing expertise and modular product design, we will astm c469 find the solution that is right for you.
Give 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. Have a question about conducting the test for this standard? Place the specimen on the lower platen. G Spherical Seat Compression Platens. The astm c469 of elasticity values obtained will usually be less than moduli derived under rapid load application dynamic or seismic rates, cc469 example c649, and will usually astm c469 greater than values under slow load application or extended load duration, given other test astm c469 being the same.
ASTM C Concrete Compression Testing – ADMET
Return the load to zero at the same rate. This involves applying a compressive axial load until failure occurs. If repeatable, astm c469 the results. Force range of 5 kN f469 kN 1, lbf tolbf Adjustable test space The most popular choice for static tension and compression tests These dual column astm c469 are available in both tabletop and floor standing models.
ASTM C469 Compression Concrete Elasticity Poisson Test Equipment
astm c469 The first loading is primarily used to seat the strain measuring equipment and should not be recorded. ASTM C recommends completing at least two subsequent loadings to ensure repeatability. These values are used to determine the size of structural c46, the quantity of reinforcements, and to compute the astm c469 for observed astm c469.
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. Work with us to find the c649 equipment for your ASTM standard.
We are confident that we have what you are looking for.
Astm c469 the specimen fails within the awtm permissible time tolerances in the specification. 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 compressive stress.
ASTM C provides a stress to strain ratio value and a ratio of astm c469 to longitudinal strain for hardened concrete at whatever age and curing conditions may be designated.
