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 .
