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 D7012C

Material

Rock

Test Property

Uniaxial Compressive Strength

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 until peak load and failure are obtained. Unconfined compressive strength of rock is used in many design formulas and is sometimes used as an index property to select the appropriate excavation technique.

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
