The purpose of this standard is to describe a test making it possible to follow over time the evolution of concrete during its setting, that is to say during its transition from the liquid state (characterized by consis ency measurements) in the solid state (characterized by mechanical resis ance measurements). The test makes it possible to study the behavior of fresh concrete, particularly in the case of the addition of setting modifiers (accelerators or retarders) or to assess the influence of other factors (temperature, hygrometric degree, etc. .).
