Place the specimen on the lower platen.

These values are used to determine the size of structural members, the quantity of reinforcements, and to compute the stress for observed strains. We are confident that we have what you are looking for. This involves applying a compressive axial load until failure occurs. Measures displacement for axial tensile, compression, and cyclic testing Gage lengths from 10 astmm to 50 mm 0.

Return the load to zero at the same rate.

ASTM C C determines the 1 chord modulus of elasticity Young s and 2 Poisson v469 ratio of molded concrete cylinders and diamond-drilled concrete cores when under longitudinal compressive stress. We are happy to help! The first loading is primarily used to seat the strain measuring equipment and should not be recorded.

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.

This will ensure uniform seating is obtained. The modulus of elasticity under static rate will be less than values found under asgm 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. Place the specimen on the platen so the axis of the specimen is aligned with the center of thrust of the spherically seated bearing d469. If repeatable, average the results. Ambient temperature and humidity should be maintained as constant as possible through the duration of this test.

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. 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 C469 Concrete Compression Testing

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. E Deflectometer Awtm Gauge. ASTM C recommends completing at least two subsequent loadings to ensure repeatability.
