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.

Place the specimen on the lower platen. The modulus of elasticity under static rate will be asmt than values found under dynamic or seismic rate and greater than values under slow load application. Standard load ratings up to kN 67, lbf ; higher ratings available upon request Platen diameters from 56 mm to mm 2.

Standard load ratings up to kN 67, lbf ; higher ratings available upon request Platen diameters available from 56 mm to mm 2. E Deflectometer 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.

ASTM C Concrete Compression Testing – ADMET

This involves applying a compressive axial load until failure occurs. This will ensure uniform seating is obtained. Work with us to find the right equipment for your ASTM standard. These values are used to determine the size of structural members, the quantity of reinforcements, and to compute the stress for observed strains.

Ensure the specimen fails within the prescribed permissible time tolerances in the specification. Measures displacement for axial tensile, compression, and cyclic testing Gage lengths from zstm mm to 50 mm 0. 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.

If repeatable, average the results. By means of our testing expertise and modular product design, we will adtm find the solution that is right for you.

ASTM C469 Concrete Compression Testing

Ambient temperature and humidity should be maintained as constant as possible through the duration of this test. E Clip On Axial Extensometer. Attach the required strain-measuring equipment compressometer-extensometers. ASTM C recommends completing at least two subsequent loadings to ensure repeatability.

Place the specimen on the platen so asfm axis of the specimen is aligned with the center of thrust of the spherically seated bearing block. G Spherical Seat Compression Platens.

ASTM C provides a stress to strain ratio value and a ratio of lateral to longitudinal strain for hardened concrete at whatever age and curing conditions may be designated.

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. Return the load to zero at the same rate. We are happy to help! Available from a 1 mm 0. The modulus of elasticity values obtained will usually be 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.
