ASTM C469 Concrete Compression Testing
E Clip On Axial Extensometer. Standard load ratings up to kN 67, lbf ; higher ratings available upon request Platen diameters from 56 mm to mm 2. Ambient temperature and humidity should be maintained as constant as possible through the duration of this test.
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.

ASTM C Compression Concrete Elasticity Poisson Test Equipment
Standard load ratings up to kN 67, lbf ; higher ratings available upon request Platen diameters available from 56 mm to mm 2. Attach the required strain-measuring equipment compressometer-extensometers. 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. 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.
How to Perform an ASTM C469 Concrete Compression Test
By means of our testing expertise and modular product design, we will help find the solution that is right for you. ASTM C provides a stress to strain ratio value and a ratio of lateral to longitudinal strain for hardened concrete c649 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.
We are happy to help! The first loading is primarily used to seat the strain measuring equipment and should not be recorded. Work atm 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. We are confident that we have what you are looking for.

These values are used to determine the size of structural members, the quantity of reinforcements, and to compute x469 stress for observed strains. This involves applying a compressive axial load until failure occurs. Return the load to zero at the same rate.
If repeatable, average the results. Place the specimen on the lower platen.
ASTM C recommends completing at least two subsequent loadings to ensure repeatability. This will ensure uniform seating is obtained.
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. G Spherical Seat Compression Platens. Force range of 5 kN to kN 1, lbf tolbf Adjustable test space The most popular choice cc469 static tension and compression tests These dual column testers are available in both tabletop and floor standing models. E Deflectometer Deflection Gauge. Measures displacement for axial tensile, compression, and cyclic testing Gage lengths from 10 mm to 50 mm 0.
