1.1 This test method covers determination of compressive strength of cylindrical concrete specimens such as molded cylinders and drilled cores.This standard has been approved for use by agencies of the Department of Defense. 1. Scope * 1.1 This test method covers determination of the compres- sive strength of hydraulic cement .3.1 This test method consists of applying a compressive axial load to molded cylinders or cores at a rate which is within a prescribed range until failure occurs. The compressive strength of . 4.1 This test method provides information regarding the behavior of cellular materials under compressive loads. Test data is obtained, and from a complete load-deformation curve it is possible to compute the compressive stress at any load (such as compressive stress at proportional-limit load or compressive strength at maximum load) and to compute the .
Significance and Use 5.1 The primary purpose of the unconfined compression test is to quickly obtain a measure of compressive strength for those soils that possess sufficient cohesion to permit testing in the unconfined state. 5.2 Samples of soils having . Standard Test Method for Unconfined Compressive Strength of Cohesive Soil .3.2.3 compressive strength—the maximum compressive stress (nominal) carried by a test specimen during a compres-sion test. It may or may not be the compressive stress (nominal) carried by the specimen at the moment of rupture. 3.2.4 compressive strength at failure (nominal)—the com-pressive stress (nominal) sustained at the moment of failure of 4.2 Compressive properties include modulus of elasticity, yield stress, deformation beyond yield point, and compressive strength (unless the material merely flattens but does not fracture). Materials possessing a low order of ductility may not exhibit a yield point. In the case of a material that fails in compression by a shattering fracture, the compressive strength has a . 5.2 The residual strength data obtained using this test method is most commonly used in material specifications and research and development activities. The data are not intended for use in establishing design allowables, as the results are specific to the geometry and physical conditions tested and are generally not scalable to other configurations.

[2 mm], and test in accordance with Test Method C 39/ C 39M. Test the specimens for compressive strength in the “as-received” moisture condition unless required otherwise by project specifications. 8. Calculation 8.1 Calculate the compressive strength of each specimen using the computed cross-sectional area based on the average4. Summary of Test Method 4.1 This test method consists of applying a compressive axial load to molded cylinders or cores at a rate which is within a prescribed range until failure occurs. The compressive strength of the specimen is calculated by dividing the maximum load attained during the test by the cross-sectional area of the specimen. 5.
