Test Method Title

Standard Test Method for Compressive Strength and Elastic Moduli of Intact Rock Core Specimens under Varying States of Stress and Temperatures

Reference Number

ASTM D7012D

Material

Rock

Test Property

Uniaxial Compressive Strength, Young's Modulus, Poisson's ratio

Description of Test

A rock core sample is cut to length, and the ends are machined flat. The specimen is placed in a loading frame and, if required, heated to the desired test temperature. Axial load is continuously increased on the specimen, and deformation is monitored as a function of load. The elastic constants are used to calculate the stress and deformation in rock structures.

Preferred Test Sample Size

Rock core specimens

Number of Test Specimens

1 or more

Test Specimen Size

Right circular cylinder, with diameter of at least 1 7/8 in and a length to diameter ratio of 2 to 2.5
