FINENESS, CONSISTENCY & SETTING TIME/ SOUNDNESS

To determine the fineness of cements, pozzolanas and other powdery materials, various international specifications recommend the use of "specific area" method. In the instrument described below, air permeability method is used to determine the specific surface as total surface area in cm²/g of material.

Vicat Method

Ref. Standards IS:2542 (Part-2), 2645, 1727, 5513, BS:12, 146, 915, 1370, 4027, 4246, 4248, ASTM C-91, C-141, C-187, C-308, C-359, C-472 & AASHTO T-129, E-131

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 predetermined 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.
