CONSISTENCY AND SETTING-TIME:-
Apparatus described below have been designed for
determining the normal consistency, standard consistency and time of setting
of cement and lime in accordance with IS, ASTM, BS and AASHO specifications.
Vicat Method:-
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.
