In the context of slump measurement, temperature is not considered a direct component impacting the slump value. Slump measurement primarily focuses on assessing the workability of concrete, which is influenced by the consistency and fluidity of the mixture.

Consistency relates to the thickness or viscosity of the concrete mix, indicating how fluid or stiff it is. Fluidity refers to the ease with which the concrete can flow. Both these factors are critical in determining the slump, as they directly affect how the concrete behaves when poured or placed. Air content, although it can influence the workability in broader contexts, is not a measure taken during the actual slump test, but it is related to the overall characteristics of the concrete mix.

Temperature, while it can influence the setting time and other properties of concrete, is not a standard consideration during the slump test itself, which is intended to provide a direct measurement of the concrete's workability without external modifiers like temperature affecting the outcome.
