Place the specimen on the platen so the axis of the specimen is aligned with the center of thrust of the spherically seated bearing block. 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.
Have a question about conducting zstm test for this standard? Ensure the specimen fails within the prescribed permissible time tolerances in the specification. 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 Clip On Axial Extensometer. If repeatable, average the results.
How to Perform an ASTM C469 Concrete Compression Test

Work with us to find the right equipment for your ASTM standard. 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. 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.
Measures displacement for axial tensile, compression, and cyclic testing Gage lengths from 10 mm to 50 mm 0. This will ensure uniform seating is obtained. Standard load ratings up to kN 67, lbf ; higher ratings available upon request Platen diameters available from 56 mm to c4669 2. Available from a 1 mm 0. G Spherical Seat Compression Platens. 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.
These values are used to determine the size of structural members, the quantity of reinforcements, and to c46 the stress for observed strains.
ASTM C, Test equipment Controls
aastm Standard load ratings up to kN 67, lbf ; higher ratings available upon request Platen diameters from 56 mm to mm 2. The first loading is primarily used to seat the strain measuring equipment and should not be recorded. E Deflectometer Deflection Gauge. Return the load to zero at the same rate.
This involves applying a compressive axial load until failure occurs. Attach the required strain-measuring equipment compressometer-extensometers. 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 recommends completing at least two subsequent loadings to ensure repeatability.
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.
