ASTM C1150-96 PDF Download

The ASTM C1150-96 standard outlines the procedure for determining the break-off number of hardened concrete. This method involves measuring the force needed to cause failure of a pre-cast or drilled core specimen, which is loaded as a cantilever.

The purpose of this test is to assess the mechanical strength of the concrete and its ability to withstand external forces. By measuring the force required for failure, engineers and researchers can determine the maximum load that the concrete can support without breaking. This information is vital for designing structures and ensuring their safety and durability.

The test method described in the standard provides a standardized approach for conducting break-off tests on concrete specimens, ensuring consistency and accuracy of results across different laboratories. It provides guidelines on the preparation of the core specimens, the loading procedure, and the calculations necessary to determine the break-off number.
