The specification for the minimum thickness of a slump cone is defined to ensure the accuracy and reliability of the slump test results. A thickness of 1.5mm is the standard requirement. This thickness helps maintain the structural integrity of the cone while allowing for secure handling and prevents any deformation that could affect the measurements taken during the slump test.

Using a cone that adheres to the specified thickness also helps ensure uniformity across different tests, as discrepancies in the cone's construction can lead to variations in the slump readings. As a result, a minimum thickness of 1.5mm ensures that the slump cone is robust enough to withstand repeated use while still being lightweight and easy to manage.

Therefore, a slump cone meeting the 1.5mm standard thickness specification is essential for obtaining consistent, accurate results in concrete work, as defined by relevant testing standards.
