Chapter 7—Analyzing strength test data, p. 214.4R-7 7.1—ASTM C42/C42M precision statements 7.2—Review of core strength correction factors . concrete in an existing structure can be evaluated using cores. This in-place strength determination is simplified Most tests are performed on manually operated concrete compression testing machines which require the operator to continuosly adjust a valve during a test so that the loading rate remains within specification. ASTM C39, Standard Test Method for Compressive Strength of Cylindrical Concrete Specimens, specifies that the loading rate fall within 0 . 2.1 ASTM Standards: 2 C31/C31M Practice for Making and Curing Concrete Test Specimens in the Field C42/C42M Test Method for Obtaining and Testing Drilled Cores and Sawed Beams of Concrete C125 Terminology Relating to Concrete and Concrete Ag-gregates C192/C192M Practice for Making and Curing Concrete Test Specimens in the Laboratory
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. Deformation and strength of rock are known to be functions of confining pressure. Method A, triaxial compression test, is commonly used to simulate the stress conditions under which .Sections 26.5.3.2 and 26.12.1.1 of ACI 318-19, ACI 301-20 “Specifications for Concrete Construction”, and ACI 311.6-18 “Specification for Testing Ready Mixed Concrete” require concrete strength tests for acceptance to be the average of at least two 6 x 12 in. (150 x 300 mm) cylinders or at least three 4 x 8 in. (100 x 200 mm) cylinders.cast from a concrete sample taken from the discharge of a truck or a batch of concrete. They are molded and cured following the standard procedures of ASTM C31/C31M and tested as required by ASTM C39/C39M. If the concrete is so prepared, cured, and tested, the results are the compressive strength of the concrete cured under controlled conditions, Abstract. The compressive mechanical response of ultra-high-performance concrete (UHPC) surpasses that exhibited by the types of concrete for which the ASTM C39 compressive strength test and ASTM C469 compression modulus of elasticity test were developed. When attempting to complete these tests on UHPC, one will likely face challenges .
