The procedure, as recommended in various standards, is for determining the quantity of water required to produce a cement paste of standard consistency. The standard consistency is attained when the 10 mm plunger of the apparatus penetrates the material to a pre-determined depth under free-fall. A new sample is prepared and tested with initial and final needles in accordance with the procedure described in various specifications. Vicat Apparatus consists of a frame bearing a movable rod with a cap at top and a Vicat mould in the form of the frustum of a cone, (80+5)70 + 5mm dia at the base,(70mm+5mm) 60 mm at the top and 40 mm high, and with a glass base plate of minimum 2.5 mm thickness with various models of Vicat apparatus as per standard specifications. Two models of Vicat Apparatus are offered
