A Vicat needle is used to determine the consistency and setting time of cement and other materials. To use it, prepare a sample of the material according to standard procedures, then place it in a mold on a flat, level surface. The Vicat needle, which has a specific weight and a pointed end, is then gently lowered onto the surface of the material until it penetrates to a predetermined depth.
