The standard, ASTM D7012-14, "Standard Test Methods for Compressive Strength and Elastic Properties of Intact Rock Core Specimens under Varying States of Stress and Temperatures," provided a detailed methodology for testing the compressive strength of rock.
John decided to download the PDF of ASTM D7012-14 and study it carefully. He realized that the standard specified the equipment, test procedures, and calculations required to determine the compressive strength of rock. Astm D7012-14 Pdf
The results were striking. The compressive strength of the aggregates was significantly lower than what the supplier had claimed. In fact, the results showed that the aggregates were not suitable for use in concrete. The standard, ASTM D7012-14, "Standard Test Methods for
The company's quality control team had been conducting tests on the aggregates, but they weren't sure if they were doing it right. That's when they remembered that ASTM International, a globally recognized leader in the development and delivery of voluntary consensus standards, had published a standard for determining the compressive strength of rock. The results were striking
