The purpose of a concrete slump cone is to measure the consistency and workability of fresh concrete. This tool provides a quick and simple way to gauge how easily the concrete can be mixed, placed, and finished. The slump test involves filling the cone with fresh concrete, removing it, and then measuring how much the concrete "slumps" or settles down. This slump value gives a direct indication of the water-cement ratio and overall mix design, which are critical factors in assessing whether the concrete is suitable for its intended application.

In contrast to the other options, checking the temperature of the concrete, assessing strength after curing, and determining the thickness of a concrete layer do not pertain to the slump cone's function. These tasks involve different procedures and equipment, such as thermometers for temperature, compression testing machines for assessing strength, and measuring tools for thickness. By focusing on workability, the slump cone plays a crucial role in ensuring that the concrete can be worked with effectively and achieves the desired properties once set.
