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 Method C, uniaxial compressive strength of rock is used in many design formulas and is sometimes used as an index property to select the appropriate excavation technique.

a prescribed range until failure occurs. The compressive strength of the specimen is calculated by dividing the maxi-mum load attained during the test by the cross-sectional area of the specimen. 4. Significance and Use 4.1 Care must be exercised in the interpretation of the significance of compressive strength determinations by this test
4.1 Cast-in-place cylinder strength relates to the strength of concrete in the structure due to the similarity of curing conditions because the cylinder is cured within the slab. However, due to differences in moisture condition, degree of consolidation, specimen size, and length-diameter ratio, there is not a unique relationship between the strength of cast-in-place . 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 .7. Compressive Strength 7.1 Test Apparatus—The compressive strength testing ma-chine shall conform to Specification C1716. NOTE 7—Previous versions of this standard have contained specific requirements for compressive strength test machines. These requirements have been replaced with reference to Specification C1716. 7.2 Test Specimens:ASTM C109 - Compressive Strength of Hydraulic Cement Mortars (Using 2-in. or [50-mm] Cube Specimens) 1. This standard is issued under the fixed designation C 109/C 109M; the number immediately following the designation indicates the year of original adoption or, in the case of revision, the year of last revision.
compressive strength of hydraulic cement and other mortars and results may be used to determine compliance with speci-fications. Further, this test method is referenced by numerous other specifications and test methods. Caution must be exer-cised in using the results of this test method to predict the strength of concretes. 5. Apparatus3.1.6 compressive strength, [F/L2], n—the maximum com-pressive stress which a material is capable of sustaining. Compressive strength is calculated from the maximum load during a compression test carried to rupture and the original cross-sectional area of the specimen.
