Final answer:
The sample of concrete for the slump test must be obtained following ASTM Standard C172/C172M. This standard details the correct procedure for sampling and mixing fresh concrete. Afterwards, the slump test should be performed according to ASTM C143/C143M to measure the workability and consistency of the concrete.
Explanation:
The sample of concrete from which the slump test is conducted should be obtained in accordance with ASTM Standard C172/C172M. This specific ASTM standard outlines the process of sampling and mixing fresh concrete which is explainable if the concrete is manufactured in a mixing truck and is discharged into a wheelbarrow, or any similar equipment for transporting concrete to the testing area.
Following the procedures according to the ASTM standard, the slump test is then conducted in accordance with ASTM C143/C143M. It is essential in determining the workability and consistency of the fresh concrete, which could indicate the ease of handling and placing the concrete.
